The Different Types of Phosphide Powder

Posted on by adminLeave a comment
Phosphide Powder Classification
Ionic Phosphates
Alkali metals, metals of the alkaline Earth, zinc, aluminium and other phosphates. You can think of these compounds as phosphine derivatives, where the hydrogen atoms were replaced by metals atoms with equal equivalence. Acids dissolve most ionic phosphates. For instance, calcium phosphide (Ca3P2) reacts quickly with water in order to form hydroxide and phosphide. Zinc Zn3P2 is a phosphide that reacts slowly in water, but readily with acid.

Metallic Phosphide
Phosphates are a mixture of most heavy metals. They have a similar composition and look to metal intercompounds and are difficult to break down by acids or water.

Phosphide Powder Application
Ferric phosphor (22-39% P) can be used to make high-strength alloy steel. Steel’s strength and resistance to corrosion are greatly enhanced by adding 0.1-0.3% phosphorus. Ferric Phosphor is a by-product from single phosphor made by the electric furnace process. In ferric phosphor, there are small amounts of silicon, chrome, alum, and other impurities.
Iridium-phosphide is a chemically stable and extremely hard material that is used to make pens.
Magnesium Phosphide releases about half of its phosphine into moist air.
Aluminum phosphide can also release highly toxic phosphine into moist air. This is why it’s used in grain fumigants.
Copper phosphide can be used as an oxidizer.
The phosphating grain can be used as a semi-conductor.

The Phosphide

Calcium phosphide
It is a reddish-brown crystal or gray granular substance with a melting temperature of approximately 1600 and a relative density of 2.51; it can also be a crystalline material. This material is soluble only in acids, but not in ethanol or ethyl alcohol. It is made by heating aluminum and carbon to reduce the calcium phosphate. It is used to make phosphine bombs, signal bombs, and fireworks. Zinc phosphide, a dark gray powder that has an unpleasant odor and a melting point of above 420 is non-combustible when ignited. The density is 4.55g/cm3(18). Rats and mice are poisoned by Zinc phosphide Baits that contain 2% to 3% zinc powder with red phosphorus at 550. Aluminum phosphide comes in a gray-yellow powder or crystal. It does not melt, sublimate, or decompose at 1000°C. The ignition temperature of the powder is around 100, and its relative density is 2,85. The product is made from aluminum powder and phosphorus red acting with electric currents or flames at 650. Aluminum phosphide should be dried, stored and released highly toxic gas when wet.

Sodium phosphide
The red crystal Na3P is highly toxic and flammable when it reacts with water. Use as a phosphating compound to prepare pesticides and phosphine. Chemical reaction produces red phosphorus by combining metallic sodium and red phosphorus.


Hydrogen phosphide
Phosphine, which is stored in compressed cylinders, is a colorless gas that’s highly toxic and flammable. Its storage pressure (522psig) is 70oF of its vapor-pressure. The gas is heavier and smells similar to fish. When traces of ethophosphate or other phosphorus-hydrides are present, spontaneous combustion occurs. Phosphine has been classified as a highly toxic, spontaneously flammable and highly toxic gas. Inhalation of the gas phosphine may affect the heart and respiratory system as well as kidneys, stomachs, nerves, and liver.

The Bayer Process-The Main Production Method of Alumina

Posted on by adminLeave a comment
Alumina Bauxite is also known as a stable aluminium oxide in the fields of mining, ceramics and materials sciences. The rapid development of our country’s electrolytic aluminium, ceramics industries, medicine, electronics and machinery will increase the demand for alumina.
There are many ways to extract alumina from ore. These include the Bayer method and other methods such as soda-lime sintering. The Bayer Process was the primary method for producing aluminum, with its output accounting for approximately 95% of total global alumina output. Although the acid method made huge progress in the 1970s it was not used by industry.



Bayer Process: A new way to produce alumina

The Austrian Bayer K.J.Bayer invented it in 1888. The principle is that caustic (NaOH solution) is used to warm alumina and dissolve it in bauxite, resulting in sodium aluminate. After the solution (red mud) is separated, the temperature of the mixture is lowered and aluminum hydroxide added as a crystal seed. After long stirring, the sodium-aluminate solution is separated to aluminum hydroxide. Then, it’s washed off and calcined in a temperature range of 950-1200. The alumina is obtained. Mother liquor is the solution that remains after precipitation.

Because gibbsite and diaspore are different in their crystalline structure, they will dissolve at different temperatures. The gibbsite-type bauxite dissolves at temperatures between 125 and 140, and diaspore-type bauxite at 240260 with the addition of lime (37%).

Bayer process alumina: advantages and disadvantages

The Bayer Process is a modern process that has been characterized by:

1. Equipment of large scale and continuous operation
2. Automation of production processes;
3. Energy-saving techniques such as fluidized roasting, high-pressure enhanced disolution and high pressure enhanced dissolution;
4. Dry purification of flue gases and aluminum electrolysis is needed for production of sandy alumina. Bayer’s advantages

The economic effect of the Bayer Process is determined by the quality of the bauxite, mainly the SiO2 content in the ore, which is usually expressed by the aluminum-silicon ratio of the ore, that is, the weight ratio of the Al2O3 to the SiO2 content in the ore. Because in the dissolution process of the Bayer Process, SiO2 is transformed into sodalite-type hydrated sodium aluminosilicate (Na2O*Al2O3*1.7SiO2*nH2O), which is discharged along with the red mud. The Bayer Process will generate about 1 kg of Al2O3 for every kilogram of SiO2 present in the ore. This is followed by 0.8 kg of NaOH. The Bayer process has a worse economic effect the lower the aluminum-silicon ration of bauxite. The Bayer Process produced bauxite with an aluminum-silicon proportion greater than 8 until the late 70s. In order to make the most of the diminishing resources of gibbsite bauxite, research and development has focused on finding new ways to save energy and using other types of bauxite.

The Preparation And Application of Tungsten Carbide Powder

Posted on by adminLeave a comment
Tungsten carbide It is composed of carbon and tungsten. The molecular formula for this compound is WC, and the molecular weight is 195.85. Tungsten carbide is a hexagonal black crystal that has a metallic luster. Its hardness and durability are similar to those of diamond. It is also a good heat conductor and conductor for electricity. Tungsten carbide is not soluble with water, hydrochloric, or sulfuric acid. However, it can be dissolved in a mix of hydrofluoric, nitric, and phosphoric acid. Pure tungsten carbide is fragile. By adding titanium, cobalt or other metals, this fragility can be reduced.

Tungsten Carbide Preparation

The tungsten is mixed in a ball-mill with carbon black and the tungsten has been pressed into a plate. It can also be heated up to 14001700 degrees in an induction oven. In the hydrogen flow, initially W2C is produced. The reaction continues at high temperature, producing WC. Or, first tungsten is decomposed thermally in a CO atmosphere between 650 and 1000degC, to get tungsten, then carbon monoxide is added at 1150degC, to yield tungsten carburide. W2C is produced by temperatures above this point.
Tungsten trioxide, WO3, is hydrogenated and then reduced to form tungsten (average particle size of 35mm). Press-forming is done by applying pressures of approximately 1t/cm2 to a mixture of carbon black and tungsten trioxide in a dry-blended ratio (for about 10 hours). Pressurized material blocks can be placed into a crucible or graphite block and heated in a hydrogen stream using pure hydrogen (with a dewpoint below -35).

As the reaction is incomplete due to a low temperature (mainly), the unreacted tungsten and intermediate W2C remains besides the WC (tungsten carburide). The tungsten must therefore be heated at the temperature above. The maximum temperature must be determined based on the particle size. For coarse particles, with an average particle diameter of approximately 150 mm the reaction takes place at a temperature between 1550 and 1650degC.

Tungsten Carbide Application

Tungsten carbide is used in many applications, including high-speed cutters, furnace structural materials for jet engines, cermet material, resistance heating components, etc.

Tungsten carbide is used in the manufacture of cutting tools, wear-resistant components, melting crucibles (for metals like copper, cobalt, or bismuth), and wear-resistant semi-conductor films.

Tungsten carbide is used for super-hard material, and also as wear-resistant material. It is a solid solution that can be formed with many different carbides. WC-TiC-Co cermented-carbide tools have been used widely. It can also reduce the sintering temp and maintain good performance when used as an additive to NbC C and TaC C ternary system carburides. It can also be used for aerospace materials.

Tungsten carbide is produced by combining tungsten anhydride with graphite under a reducing atmospheric at temperatures between 14001600. By hot pressing sintering, or hot isostatic sintering, dense ceramic products can also be achieved.

The application and features of Graphite

Posted on by adminLeave a comment
Ever since we learned our first alphabet, pencils have been used to write. You may have wondered why the lead tip or the silvery black part of the pencil are rolled on wood. It’s none other than The graphite is a mineral. Yes, this semimetal is found in pencils. It is also a vital element in many products and industries.Graphite, a metal sub-metal, is derived as a result of metamorphosing rocks containing carbon. The flaky form is obtained from these carbon rocks. It is one the softest metals, and it is carbon in a stable form. It is an excellent conductor for electricity, and it also works well as a lubricant. Although it is soft, it has no elastic or stretch properties. These include the industrial and automotive sectors. We now know that graphite is an element. Let us look at the facts about graphite.
Does the powder come from simply crushing raw graphite to crystals? Though the name suggests otherwise, graphite does not refer to a natural or raw powder. The graphite is a mineral. . What is the form of graphite powder then?
Granulated graphite is also referred to as powder. The powder can also be made using recycled graphite. The powder can also be produced from scrap material that is left over after a manufacturing process or crushing. This process is explained by the fact that graphite electrodes are discarded after lathe turnings and cutting of manufactured pieces.
During the process of replacing the old electrode with a brand new one, the old electrode remains. What is crushed to make the alumina? The graphite is a mineral. powder. The powdered version is also obtained by heating the powdered petroleum. This is heated above graphitization temperatures and then other procedures are performed to obtain powdered Graphite.

The advantages and disadvantages
Graphite is also used as a powder in paints, and other coating materials. This powder is used to boost the carbon content of certain metals, such as steel. It can also be used as a lubricant to protect surfaces from damage caused by friction. In powder form, the graphite atoms tend to connect to one another like a grid. The stacking of the atoms creates layers. What happens next is that air and water become trapped in the layers.
The lubricating effect is due to this. The powdered form of graphite can be used to make a slurry for many purposes, including oil drilling, brake linings or carbon batteries. Due to its dryness and lubricating qualities, this powder is used by many industries. Graphite’s high melting point allows it to withstand even high temperatures.
Black lead for pencils is another popular use of powdered lead. Although we call it lead, this is actually powdered lead metal. The graphite is a mineral. . Locks and keys also use powdered forms of graphite to lubricate their mechanisms. This powder is also a favorite of many artists who use it to create artwork.
The powdered graphite may cause corrosion on certain metals. It can also stain the object that has been lubricated using graphite. We are all familiar with graphite, but we don’t know much about it in powdered form. Although certain industries have banned the use graphite, its many uses make it valuable to most industries.
