Zirconium Oxide ZrO2 powder CAS 1314-23-4

About Zirconium Oxide ZrO2 powder:
Zirconium oxide (ZrO2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite. A dopant stabilized cubic structured zirconia, cubic zirconia, is synthesized in various colors for use as a gemstone and a diamond simulant. Our company also can supply zirconium oxide ceramic(zro2 ceramic) products

If you want to know zirconium oxide price, please send inqury to sales1@rboschco.


Zirconium oxide is chemically unreactive. It is slowly attacked by concentrated hydrofluoric acid and sulfuric acid. When heated with carbon, it converts to zirconium carbide. When heated with carbon in the presence of chlorine, it converts to zirconium tetrachloride.
Zirconium dioxide is one of the most studied ceramic materials. ZrO2 adopts a monoclinic crystal structure at room temperature and transitions to tetragonal and cubic at higher temperatures. The change of volume caused by the structure transitions from tetragonal to monoclinic to cubic induces large stresses, causing it to crack upon cooling from high temperatures.

Three phases are known: monoclinic below 1170 °C, tetragonal between 1170 °C and 2370 °C, and cubic above 2370 °C. The trend is for higher symmetry at higher temperatures, as is usually the case. A small percentage of the oxides of calcium or yttrium stabilize in the cubic phase. The very rare mineral tazheranite, (Zr, Ti, Ca)O2, is cubic. Unlike TiO2, which features six-coordinated titanium in all phases, monoclinic zirconia consists of seven-coordinated zirconium centers. This difference is attributed to the larger size of the zirconium atom relative to the titanium atom.

The ZrO2 band gap is dependent on the phase (cubic, tetragonal, monoclinic, or amorphous) and preparation methods, with typical estimates from 5–7 eV. A special case of zirconia is that of tetragonal zirconia polycrystal, or TZP, which is indicative of polycrystalline zirconia composed of only the metastable tetragonal phase. Feel free to send an inquiry to get the latest price if you would like to buy Zirconium Oxide ZrO2 powder in bulk.

Performance of Zirconium Oxide ZrO2 powder :
The chemical property of zirconium dioxide is inactive, and has the properties of high melting point, high resistivity, high refractive index and low coefficient of thermal expansion, making it an important high temperature resistant material, ceramic insulating material and ceramic sunscreen, and it is also the main part of artificial drills. raw material. The band gap is about 5-7eV.

How is Zirconium Oxide ZrO2 powder produced?
The industrial refractory material is fully stabilized zirconia, and most of the electric mete is made. Carbon and stabilizable calcium oxide were added to the zircon meter fuse, and the zirconia and calcium oxide was used to generate a solid solution, and then stably zirconia was produced while the zirconia and the calcium oxide was used to form a solid solution. Stable and partially stabilized zirconia used in fine ceramics is generally prepared with wet.

The most mature and commonly used is neutralization. The purified chloride zirconium is dissolved with pure water, filtrate the insoluble matter, adjust the zirconium concentration in the solution, and add the required amount of a cerium chloride solution (or other rare earth metal or alkaline chloride solution), add ammonia water Medium and precipitation. The precipitate was washed with hot water and then filtered, dried and calcined. Ultrafine stabilized zirconia powder can be obtained by treating the calcined product.
Partially stabilized zirconia is to control the amount of added stabilizer, which is not sufficient to achieve complete stability. Partially yttria zirconia has high strength and thermal shock resistance, and there is a relatively wide application in structural ceramics.

Zirconium Diboride Ceramics

Posted on by adminLeave a comment
What is Zirconium Diforide? Zirconium hoboide The chemical formula for Zirconium diboride is ZrB2. Zirconium Diboride can be described as a type of covalent high refractory ceramic having a hexagonal crystal.
ZrB2 can be used as an ultra-high temperature ceramic, UHTC, with a melting points of 3246°C. Its relatively low density (about 6.09 g/cm3), and excellent high-temperature stability make it suitable for high-temperature aerospace applications like rocket propulsion systems or hypersonic flight.
It’s an uncommon ceramic that has high thermal and electric conductivity. This is similar to the hafnium and isomorphic Titanium.

ZrB2 parts can be hot-pressed, which means that they are heated to a powder before being machined. Covalentity of ZrB2 and surface oxides can cause problems in ZrB2 sintering. This causes grain to become coarser before it is densified during sintering. While pressureless ZrB2 can boost the sintering force via the reaction between sintering additions carbon and boron with surface oxidess, the mechanical properties are less than that of hot-pressed ZrB2.

You can add 30 vol% SiC (ZrB2) to increase the oxidation resistance. The protective oxide layer is very similar to protective alumina.

ZrB2 is used for ultra-high-temperature ceramic matrix composites (UHTCMCs).

Zirconium Diboride ZrB2 Ceramics
The high melting points and high conductivity of zirconium-diboride ceramics make them a valuable resource for nuclear control materials and composites.
Additionally, it is more conductive than many other ceramic materials. It can also be used in wire cutting to create complex-shaped parts.

Zirconium Diboride Uses
1. Refractory material
ZrB2 is a great special refractory substance that can be used to make casting molds, high-temperature temperature thermocouple protector bushings, and the crucible for metallurgical material. The airtightness and conductivity of ZrB2 ceramic are not great when it is used for thermocouple shielding. It must be combined to an aluminum oxide outer casing in order to perform temperature measurement. You can use the thermocouple sleeves of this material in brass and molten steel melt for long periods. ZrB2 ceramics may also be used in refractories as antioxidants.
2. Materials for electrode
ZrB2 can be used for electrodes, electric contact material, and thermocouple electrodes. A casing thermocouple material was developed in 1994 by researchers that was compatible with ZrB2 as well as graphite. The ability to work under an oxidizing atmosphere (1200-1600) has been demonstrated by experiment. A large value thermocouple, at 70mV at 1600 is possible, as well as a very high thermoelectric potential rate. The thermocouple can be used to measure temperature in special circumstances where a metal thermocouple or radiation thermometer is not available.
3. Andere
ZrB2 has an excellent wear resistance and is used for cutting tools. ZrB2 is a highly resistant material that has attracted a lot of attention due to the fact it can withstand corrosion.

It is a stable powder that is stable to air and water under normal conditions. It reacts violently with oxidants and strong acids. It burns smoothly during ignition, begins to decompose at 300 ° C in a vacuum, and completely decomposes at 500-700 ° C.

How is Zirconium Hydride ZrH2 Powder produced?
The metal is interacting with hydrogen to form zirconium hydrogenide. Sponge metallic zirconium with a purity of 99.8% was heated to high purity hydrogen (99.999%) to 400 to 600 ° C, directly reacted, ie, zirconium hydrogen fluid. The reaction is an exothermic reaction. This reaction also occurs even at room temperature, and uniform integral hydrogenation is usually achieved by annealing at a temperature of 400-600 ° C for several hours to several weeks. At room temperature, zirconium hydrogenide in the air, even in a high vacuum, will be rapidly oxidized. The formed nano-thin oxide layer prevents oxygen from further diffused into the material, so changes caused by oxidation can generally be ignored. Or reduce zirconium dioxide at 600 ° C in a hydrogen stream, and zirconium hydride can be obtained.

Why Hafnium Carbide Can Form Solid Solution with Many Compounds?

Posted on by adminLeave a comment
What is Hafnium Carbide? Hafnium carbide This gray solid needs to be stored at room temperature. Hafnium carbonide is capable of forming a solid solution when mixed with other compounds such as ZrC or TaC. As an example, HfC-4TaC’s composite carbide has two phases. One phase is the eutectic form of hafnium carbonide tantalum caride. The second phase is a needle-like phase of free graphite with a ratio of 50 to 1. This “nearly eutectic” hafnium cadmium (HfC), product has excellent thermal stability and high melting points. You can use it as the throat material for a rocket tube. Hafnium carbide is usually made from hafnium oxide (HfO2), carbon and an inert- or reducing atmosphere. It is heated to 1900-2300 degrees Celsius. Hafnium carbonide can be combined with many other compounds (such ZrC, TaC etc.). ).


Introduction to Hafnium
Hafnium is often found in nature alongside zirconium. Zirconium minerals that contain hafnium all include zirconium. Hafnium, zirconium and both are very similar. In stone, beryllium zircon may contain as much as 15% HfO2. Metamorphic zircon can also contain more than 5% HfO2. Both of these minerals do not have much reserves so they are rarely used in industry. Hafnium can be mainly extracted from zirconium. To avoid accidental combustion, sponge hafnium must be carefully removed from the crucible. You should break large pieces of sponge hafnium down into small, manageable pieces. These can be used to make consumable electrodes and melt them into ingots. This should prevent sponge hafnium from spontaneously combusting during crushing. Further purification of sponge haffnium follows the same procedure as for titanium and zirconium using the iodide-thermal decomposition process. Zirconium has slightly different control conditions. Keep the sponge hafnium blocks in close proximity to the iodization tanks at 600. For comparison, the temperature at the centre of the hot wire is 1600. That is more than 1300 for making a zirconium “crystal rod”. Forging, extrusion and tube drawing are some of the steps involved in molding hafnium.

Hafnium carbide’s main uses
It is used primarily to produce control rods for nuclear power plants. Pure hafnium, which is a plastic material, can be processed at high temperatures and resists corrosion. It’s an important component of the atomic energy sector. Hafnium, which has a high thermal neutron capture cross section, is an ideal neutron absorber. This can also be used to protect atomic reactors and as a control rod. Hafnium can also be used to propel rockets. The cathode of Xray tubes can be made from it in the electrical sector. Hafnium and other alloys can be used for the protection of frontal layers on rocket nozzles as well as glide reentry airplanes. HfT alloys can also be used in the manufacture of tool steels or resistance materials. Hafnium, an additive element, is used in heat-resistant alloys like tungsten and molybdenum. HfC, due to its high hardness as well as melting point can be added to cemented carbides. 4TaC* HfC, which is the most melting compound, has a melting point of 4215.

Hafnium Carbide: Price
Hafnium Carbide’s purity and particle size will impact the price. The purchase volume may also have an effect on the cost. Large quantities of smaller amounts will result in a lower price. On our official website, you can see the price for Hafnium Carbide.

What’s ZrC powder exactly?
Zirconium carbid is an extremely hard material that has high melting points and good high-temperature resistance. You can use them to create alloy steel, and as solid fuel in rocket engines. This is also the raw material used to make zirconium metal or zirconium trioxide, as well as fine ceramic materials.
This material has a strong ZrC-C covalent bond which gives it a very high melting temperature (3530degC), high module (440 GPa), as well as a 25 GPa hardness. ZrC’s density is 6.73g/cm3 lower than that of other carbides, such as TaC (14.75 g/cm3) or WC (15.8g/cm3). ZrC may be used for supersonic or rocket/hyper-jet aircraft.


Method of production for zirconium carbonide
Both technetium oxide (or charcoal) are the raw materials. They are combined, and then heated in a hydrogen atmosphere to 2400. Mixing zirconia dioxide or carbon black is also possible. They can be molded under pressure and heated to 1800 in an Induction Heating graphite Crucible. Once the hydrogen atmosphere has passed, they are added to Iy2% carbon noir and annealed at 1600 1900 in vacuum to make zirconium carbonide. You can also mix zirconium dioxide and magnesium, then heat to 750 and pickle with hydrochloric acids to extract byproducts.
Another method of manufacturing is chemical vapor repositioning. The process involves heating the zirconium sponge, and then decomposing the gas. The preparation of composite materials is one way to increase the resistance to oxidation. ZrC/ZrB2 is the preferred composite material. These composite materials are capable of working at temperatures above 1800 degrees Celsius. This situation can be improved by using another material, like TRISO fuel particle as a barrier.

An Ultra-high Temperature Structural Ceramic Material: Zirconium Diboride Ceramics

Posted on by adminLeave a comment
What is zirconium Diboride? Zirconium boreide is a chemical and has the molecular formula ZrB2. Nature gray hard crystal. The three main components of zirconium Boride are zirconium monoboride (zirconium diboride), zirconium trimoride (zirconium triboride) and zirconium triporide. The stability of zirconium boride in wide temperatures is limited to the diboride. The majority of industrial production uses zirconium boride. Zirconium dioxide is a hexagonal or gray crystal, powder, or crystal with a relative density of 5.8. The melting point at 3040°C is 3040°C. High resistance to thermal shock, high resistance to oxidation, and good resistance at low temperatures. Metallic luster. The melting point is approximately 3000degC.

Making Zirconium Diboride Pulver

ZrB2 powder can be prepared primarily using high-oxide or zirconium for boronization. Traditional synthesis involves the use of a high-temperature induction furnace, resistance furnace to achieve oxide carbothermal reducibility. While this is a straightforward process, it is not as efficient. Also, at around 1800°C, the quality of synthetic powder is less pure and the particle sizes are larger. , Poor sintering activity. Methods such as carbothermal reduction and high-temperature auto-propagation methods, mechanical alloying methods, ceramic precursor cracking techniques, and liquid phase methods, among others, are available. These are the most common now.

Zirconium Diboride ceramic Materials

Zirconium Diboride Ceramics are highly valued for their use in composite, high-temperature, structural, and electrode materials. These include turbine blades, and magnet fluid power generation electrodes for the aviation industry. Additionally, it is more conductive than other ceramic materials. It can also be used in wire cutting to create complex shapes.

Refractory

ZrB2 ceramics make excellent special refractory material, and can be used for high-temperature thermocouple protective sleeves, casting moulds, metallurgical crucibles, and other purposes. These ceramics aren’t very conductive and leaky when they are used for thermocouple protection sleeves. For accurate temperature measurement, the thermocouple protection sleeves must be used in conjunction with an alumina inner shirt. You can use the thermowell for extended periods in brass and molten metal melt. ZrB2 ceramics may also be used to protect refractory materials.

Electrode materials

ZrB2’s low resistance and electronic conduction conductive mechanism make it suitable for electrode materials and electric shock materials. It can also be used to create metal thermocouple electrodes or high-temperature heating elements. A sleeve type thermocouple material was developed by researchers in 1994. It is paired with ZrB2 (graphite) and it can be used for high temperature heating elements. Research has shown it works in an oxidizing environment at 12001600°C. This thermocouple can also be used for continuous temperature measurements in special circumstances where other metal thermocouples or radiation thermometers may not work. It makes a great thermocouple. Rmcplant (aka. Advanced material by Rmcplant . With over 12 years’ experience, Rmcplant is an established global supplier of chemical material.
