Iron Carbide Features

Iron carbide has a high conductivity and is an excellent material for lithium-ion batteries. It also exhibits electrochemical stability. In addition to its high hardness and stability, lithium-ion batteries can be used in extreme conditions.

Transition Metal Carbide Nanostructures Attract Attention

The nanostructures of the transition metal carbides have received much attention in recent years. This is especially true for iron carbide nanomaterials due to their excellent stability, high catalytic efficiency, and good biocompatibility. Features: Has important application potential for nanomagnetism and Tropsch catalysis (Tropsch), electrochemical energy storage conversion and storage as well as biomedicine. Currently used preparation methods like solid-phase reaction methods, sonochemical method, and Sol-gel methods often result in agglomeration or difficulty with phase control.

Iron Carbide Catalyst: Application

Zhao Yujun’s Tianjin team has been making breakthroughs by using Fe5C2 catalysts in the DMO system to produce alcohol. The researchers developed an innovative hydrogen and mixed gas carbonization, then obtained a relatively durable iron carbide catalyst mostly composed of Fe5C2 within a reaction atmospheric.

Further studies found that the DMO hydrogenation reaction route using Fe5C2 was different from that of copper-based catalysts, in part because Fe5C2 could selectively activate -OH on the intermediate product methylglycolate (MG), resulting in methylacetate (MA) being produced instead of ethylene-glycol (EG) by copper-based cats. MA can be further hydrogenated on Fe5C2 with high selectivity to produce alcohol. Fe5C2 did not have significant CC bond-breaking activity. The higher reaction temperature (260 degrees Celsius) resulted in a 90% yield of ethanol, while the by-products were mainly MA. Fe5C2 catalysts are clearly superior to copper-based catalysts in terms of performance.

Its melting point is 2692degC. It also has good thermal and mechanical properties, as well as good corrosion resistance. It has a melting point of 2692degC. Water and lye are insoluble. Nitric acid, hydrofluoric and sulfuric acids are slightly soluble.
The catalytic types of molybdenum carbide:
1. Hydrogenation Reaction
2. Hydrodenitrogenation HDN & hydrodesulfurization HDS reactions
3. Isomerization is a reaction.
4. Hydrocarbon conversion and Synthesis reaction
5. Applications in ammonia syntheses
Preparation of molybdenum carbide
Preparation principle: Mo+C- MoC
The two elements may be directly combined, or they can be prepared through the reaction of molybdenum oxide and molybdate under a reducing atmospheric at around 800degC.

Applications of Molybdenum Carbide
In terms of the global structure of consumption, molybdenum does indeed work with iron. In western developed countries, 80% of molybdenum demand comes from steel. Stainless and low-alloy metals absorb 30% of the molybdenum. Drill bits and cutting tool accounts for 10%. Cast steel makes up 10%. The remaining 20% is consumed by molybdenum chemicals and molybdenum lubricants, as well as petroleum refining. The United States consumed 75% molybdenum in 1998.
In addition to electronics, metal processing, and aerospace industries, molybdenum based alloys have been used more frequently.
1. Molybdenum Alloy
TZM is the alloy with the highest strength and most comprehensive properties. The United States uses TZM for turbine disks in engines and molybdenum is used for 15% of total molybdenum. The production of molybdenum in my country, including TZM molybdenum alloy, is not less than 22 different grades. Early 1990s, my country’s production of molybdenum alloys and molybdenum materials was around 200 tons.
TZM & TZC Molybdenum Alloys offer superior mechanical properties to pure molybdenum. They are widely used for high-tech moulds, structural parts, and other high-tech applications. In the early 20th century, we were able to make hot-perforated plugs from various seamless steel pipes. The sintered molybdenum sinter plugs manufactured using powder smelting reduce the raw material consumption (50%) and increase the service life 1.5 to 2x.
The seamless tube of molybdenum alloy (containing 50% Re), has excellent high-performance and can be used near its melting point. It can also be used to make the brackets, rings, grids, and other parts for the thermowell as well as the cathode.
It is easier to process molybdenum than tungsten. Therefore, plates, strips, foils, etc. Tubes. rods. wires. profiles. etc. Used in electronic tubes, electric light source parts (support material), metal processing tool (die-casting dies, extrusion dies forging dies perforated plugs liquid metal filter screens), turbine discs etc. Used in many components.
2. Alloying components of steel
The use of molybdenum as an alloying component, along with nickel and chromium can help reduce the embrittlement which occurs during heat treatment in alloy steels. United States took the lead by using molybdenum in high-speed alloys instead of tungsten to solve the lack of tungsten. Molybdenum, according to calculations has twice the “capacity”, of tungsten. The steel that contains 18% tungsten is replaced by steel that contains 9% molybdenum. Molybdenum’s role in stainless steel is to enhance corrosion resistance, strength and weldability. You can see that molybdenum has a major role to play in the steel sector.
Other Uses
Molybdenum exhibits a very low vapour pressure when working at the pressure and temperature of a vacuum furnace. Molybdenum is the material that causes the least contamination to the materials in the furnace.
Due to its high strength, molybdenum makes the ideal electrode in glass manufacturing. It is also the best material for processing and equipment when rapid heating occurs. Because molybdenum is chemically incompatible with most glass components, it will not produce harmful color changes due to the small amount of molybdenum that may be dissolved in a glass melting tank. As a heating electrode in a glass melt furnace, it can last up to 3 or 5 years.

Tantalum Carbide ceramic is a ceramic that contains a seven-crystal phase of Tantalum Carbide

Posted on by adminLeave a comment
What is Tantalum Carbide? Tantalum Carbide(TaC) is a binary compound consisting of Tantalum and carbon, and its empirical formula is TaCX, where X usually varies in a range of 0.4 to 1. They are extremely hard, brittle, metal-conductive refractory ceramic materials. They are a brownish-gray powder and are usually sintered.
As an important cermet material, Tantalum Carbide is used commercially in cutting tools and is sometimes added to tungsten Carbide alloys
A Tantalum Carbide ceramic is a ceramic that contains a seven-crystal phase of Tantalum Carbide. The chemical formula is TaC, face-centered cubic lattice. The theoretical density was 1.44, the melting point was 3730-3830 deg C, the thermal expansion coefficient was 8.3×10-6, the modulus of elasticity was 291GPa, the thermal conductivity was 0.22J/cm*S* C, and the peak melting point of Tantalum Carbide was around 3880 deg C, depending on the purity and measurement conditions. This value is the highest among binary compounds. Only hafnium carbide has a slightly higher melting point, about 3942 deg C, while hafnium carbide has a melting point comparable to TaC.

TaCX powders of the required components are prepared by heating a mixture of tantalum and graphite powders in a vacuum or in an inert gas atmosphere (argon). Heating at approximately 2000degC is performed using a furnace or an arc melting device. Another method is to reduce tantalum pentoxide with carbon in a vacuum or hydrogen atmosphere at 1500-1700degC. This method was used to prepare Tantalum Carbide in 1876, but the lack of stoichiometric control of the product reported the direct production of TaC from these elements by self-spreading high-temperature synthesis.
The bonding between tantalum and the carbon atoms in carbides is a complex mixture of ions, metals, and covalent contributions. These carbides are very hard and brittle materials due to their strong covalent composition. For example, TaC has a microhardness of 160-2000 kg/mm2[16] (~ 9mohs) and an elastic modulus of 285 GPa, while the corresponding values for tantalum are 110 kg/mm2 and 186 GPa.The hardness, yield stress and shear stress increase with the increase of the carbon content of TaCX.
Tantalum Carbide is electrically conductive to metals, both size and temperature-dependent.TaC is a kind of superconductor with high transition temperature Tc = 10.35 K.
How strong is tantalum carbide?
By testing Vickers hardness, fracture toughness, and relative density of a series of samples, it can be confirmed that the TaC possesses the best mechanical properties under 5.5 GPa and 1300 degC. The relative density, fracture toughness, and Vickers hardness of TaC are 97.7%, 7.4 MPa m1/2 and 21.0 GPa, respectively.

What is tantalum carbide used for?
Tantalum Carbide was chemically stable and insoluble in acids. Antioxidant ability is strong.TaC is usually synthesized from tantalum pentoxide and carbon black in an inert or reductive atmosphere, as a brass powder. The products with high density and metallic luster can be made by hot pressing sintering. Used as additives for aerospace materials and cemented carbide. Tantalum Carbide is a light brown metallic cubic crystal powder in the sodium chloride type cubic crystal system. It is insoluble in water, insoluble in inorganic acids, soluble in a mixture of hydrofluoric acid and nitric acid and can be decomposed. It has strong oxidation resistance and is easy to be melted and decomposed by potassium pyrosulfate. Electrical conductivity is large, the resistance at room temperature is 30O, showing superconductivity.
What is tantalum carbide used for? Tantalum carbide is widely used as a sintering additive in ultra-high temperature ceramics (UHTCs) or as a ceramic reinforcement in high-entropy alloys (HEAs) due to its excellent physical properties in melting point, hardness, elastic modulus, thermal conductivity, thermal shock resistance, and chemical stability.
Tantalum Carbide is used as an additive for powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear alloy tools, tools, molds and wear-resistant structural parts to improve the toughness of alloys. Titanium Carbide’s sintered body is golden yellow and can be used as a watch ornament. Tantalum Carbide was also used as an inhibitor of grain growth in sintered cemented Carbide with a density of 14.3g/cm3.

Is tantalum carbide toxic?
Tantalum Compounds: The systemic toxicity of tantalum oxide, as well as that of metallic tantalum, is low, which is probably due to its poor solubility. Carbides: Pure carbon has extremely low toxicity to humans and can be handled and even ingested safely in the form of graphite or charcoal.
Poseidon is an unmanned deep submersible
In 2016, a team at Imperial College London found that Tantalum Carbide (TaC) and hafnium carbide (HfC), a ceramic material with the highest known melting point, can withstand temperatures of nearly 4,000 deg C. The melting points of Tantalum Carbide and hafnium Carbide were determined by a novel laser thermal technique and the maximum melting points at 8:2 were 3768 deg C, 3958 deg C and 3905 deg C, respectively, the journal Scientific Reports reported.
Tantrum Carbide and hafnium Carbide are better at resisting high temperatures than any other material known. They protect a spacecraft from the extreme heat of exit or re-entry.
Researator Dr. Omar Sediroth Baraza said the spacecraft nose cap and scientific equipment carried by spacecraft require high-temperature resistant materials, and that Tantalum Carbide, or hafnium Carbide, could be used for future supersonic missions. It could also be used to make shells for supersonic aircraft that could fly from London to Sydney in just 50 minutes, opening up new business opportunities in countries around the world.

Magnesium Chloride Solution

Posted on by adminLeave a comment

magnesium chloride solution is an extremely soluble form of magnesium. It is used as a source of magnesium in molecular biology applications, including PCR reactions and buffers. It is also known for its ability to facilitate cell lysis. It is produced under cGMP regulations and is sterile.

Magnesium is an essential nutrient that can be found in foods such as dark leafy vegetables. It is also available as a dietary supplement in the form of tablets, liquid or powder. Magnesium supplements are often taken to improve symptoms of low magnesium levels, such as muscle cramps and fatigue. It is also believed to improve sleep and digestion, as well as boost endurance and reduce anxiety.

DOT uses a magnesium chloride solution to de-ice roads when it snows. The department says it has seen fewer crashes and complaints since switching to the chemical mix. But some residents say the chemical is corrosive to cars and other vehicles, and that adding a rust inhibitor could help.

When dissolved in water, magnesium chloride forms an acidic solution because of the replacement of hydrogen by a metal atom. The value of this acidity is measured on a pH scale, with neutral solutions at 7. HCl is an example of an acid that is replaced by a metal atom to create a salt—in this case, sodium chloride (NaCl). Most salts are basic in the aqueous state, with the exception of hydrochloric acid, which is reduced to metallic chlorine and hydrogen gas when electrolyzed in molten salt.

The Properties and Main Application Fields of Microsilica

Posted on by adminLeave a comment
What is micro silica vapor?
Micro-silica Also known as silica or condensed fume, fume is a form of silica. The mine thermoelectric oven produces many gases, including SiO2 and SiO2, when ferroalloys (metal silica) are used to melt ferrosilicon. It is formed through rapid oxidation. It is produced by large-scale industrial melting. It is necessary to recycle this entire process with the help of dust removal equipment and environmental protection gear. Encryption equipment is needed because of the low density.

What are the main applications of microsilica?

It is used widely in the refractory industries because it has excellent properties like high refractoriness. It is mainly utilized to prepare high temperature ceramics, ladle material, high temperature wear-resistant materials and refractory castables. Wang Tao et al. By using micro-silica and Al2O3 powder in a 3:2.5 ratio and a 1450degC sintering heat, they prepared high-purity mullite porous ceramics. Its compressive strength is 260.93MPa. The porosity of the material is 21%. The micro-silica can improve bulk density, strength, cohesion, and high temperature performance of refractory products. It can also be used to extend the service life and achieve internal digestion of dust produced by ferrosilicon or industrial silicon smelting companies.
Several North American companies also use mixed micro-silica and silica fume pellets for the reduction of electric furnaces and silicon melting. They found the silicon recovery is normal and that the unit product’s energy consumption is unchanged. Elkem in Norway will agglomerate micro-silica with water into pellets about 4 cm long, which are then reduced and smelted directly in an electrical furnace without any roasting or dryness. Sintered ore can be produced at a higher temperature without any problems such as bursting. In a Russian factory, micro-silica fumes and liquid waste from paper pulp are mixed into pellets. They then undergo reduction smelting using an electric furnace. This production shows that pellets can be transported without breaking because they are more durable than other materials. In Northern Europe, an enterprise that produces chromium used the microsilica powder slurry from the electric furnace wet silicon smelting method to mix with the chromium ore and pelletize. The micro-cassia was found to improve the cohesiveness of chromium pellets.

The majority of companies in the metalworking industry use microsilica fume to return materials. While this method can reduce environmental pollution due to micro-silica, it doesn’t fully exploit the magical properties of micro-silica. This is an extensive use.

The Properties And Preparation of Lithium Sulfide Powder

Posted on by adminLeave a comment
Lithium Sulfide This crystal ranges in color from white to golden. It is easily oxidized and can absorb moisture from the atmosphere. It should be stored in a dry atmosphere.

Lithium Sulfide Properties:

The molecular formula for lithium is Li2S. This is a sulfide form of lithium. The molecular weight is 45.95. The crystal is white to yellow with an inverse structure of fluorite. The melting and boiling points of lithium sulfide are 938degC & 1372degC respectively.
Lithium sulfide dissolves easily in water, is soluble when mixed with ethanol, but insoluble when mixed with alkali. Lithium Sulfide could be used in lithium-ion rechargeable batteries as an electrolyte.

Lithium Sulfide absorbs air vapor and dissolves it, releasing a highly toxic gas called hydrogen sulfide. Hydrogen sulfide is released when lithium sulfide is separated with acid. Lithium can also react violently to nitric and hydrobromic acids, but only after heating. Lithium reacts slowly with concentrated acid sulfuric, but violently with diluted sulfuric acid. When heated to 300degC or more in the air, lithium sulfide oxidizes by oxygen, but it does not produce sulfur dioxide. Instead, it produces lithium sulfate.

Lithium Sulfide Preparation:

You can prepare Lithium Sulfide in a number of ways.
Historically, carbon or hydrogen were used to reduce lithium-sulfate by heating, resulting in lithium-sulfide.

The ethanol-adduct lithium hydrosulfide can be decomposed by lithium ethoxide to form lithium sulfide.

Some people have used lithium pentoxide with hydrogen sulfide as a reaction to create lithium hydrogensulfide. Then, they heated it in vacuum and decomposed the lithium hydrogensulfide into lithium sulfide.

Anhydrous lithium sulfide of high quality can be made by reacting metallic Lithium with Hydrogen Sulfide in Tetrahydrofuran.

The Preparation And Application of Aluminum Carbide Powder

Posted on by adminLeave a comment
Aluminum carbide The molecular formula of Al4C3 is used to describe this inorganic compound. Aluminum carbide comes as a yellow, greenish gray or white crystal block. It’s hygroscopic. Aluminum carbide powder decomposes in high temperatures, and is then dissolved by cold water into aluminum hydroxide and methane.

The preparation of aluminum carbide

Aluminum carbide is produced by heating alumina with coke in a furnace. Aluminum carbide Al4C3 comes from the direct combination of two metals at high temperatures.
Then, spread carbon powder over the top of a tightly packed layer of heavy smoke black, 6 parts aluminum powder and pine essential oil. The crucible is covered with a cover, and any gaps are smeared in refractory dirt mixed with asbestos fibres. After pre-drying the crucible, the mixture should be heated to a temperature no lower than 1200degC. Higher temperatures can help the reaction progress.

After cooling, the product will be treated with dilute alkaline or hydrochloric acids (or diluted hydrochloric solution) to remove excess aluminium. After obtaining the aluminum carbide as a fine powder, it is washed to remove the aluminum chloride. Alcohol is then used to quickly wash away the water. The product is then dried in a box set at 80-90degC. The product contains an excessive amount of aluminum chloride.

Aluminum carbide itself is colorless. However, the products that are made using the above method can have different colors because of impurities.

A pure product free of aluminum nitride is obtained when the calculated amount (of aluminum and soot) is calcined with hydrogen. This calcination is carried out between 1800degC and 1900degC, for two to three hours. The resultant material is then ground, and again calcined to the temperature above.

Aluminum Carbide Application

Aluminum carbide has many applications, including in the production of methane and catalysts. Other typical uses of aluminum carbide are:
1. When combined with silicon carbide, the finely distributed aluminum carbide in the aluminum matrix reduces the tendency of material to creep.

2. The aluminum-aluminum carbide composite material can be made through mechanical alloying by grinding graphite and aluminum powder together.

3. Aluminum carbide may be used in high speed cutting tools. It is hard almost as much as topaz.

4. Aluminum carbide, used as a firework additive, can be used, for instance, to produce the effect of fireflies.
