Zirconium Carbide Properties
About Zirconium Carbide Powder:
Zirconium carbide ZrC is an extremely hard refractory ceramic material that is commercially used for cutting tooltips. It is usually processed by sintering. Zirconium carbide is brittle. Zirconium carbide melting point is 3540°C. Zirconium carbide boiling point is 5100°C. The apparent density is 6.70 g/cm3. Mohs hardness 8-9. Insoluble in cold water and hydrochloric acid. It is soluble in hydrofluoric acid and hot concentrated sulfuric acid containing nitric acid or hydrogen peroxide. It reacts with chlorine at high temperatures to produce zirconium tetrachloride. At 700°C, it burns in the air to produce zirconia. Do not react with water.
ZrC powder is a gray metal powder with a cubic crystal structure. Highly corrosion resistant. The group IV interstitial transition metal carbides are also members of ultra-high temperature ceramics (UHTC). Due to the presence of metal bonds, ZrC has a thermal conductivity of 20.5 W/m·K and electrical conductivity (resistivity of ~43μΩ·cm), both of which are similar to zirconium metal. The strong Zr-C covalent bond gives the material a very high melting point (~3530°C), high modulus (~440 GPa) and hardness (25 GPa). Compared with other carbides such as WC (15.8 g/cm3), TaC (14.5 g/cm3) or HfC (12.67 g/cm3), ZrC has a lower density (6.73 g/cm3). ZrC seems to be suitable for reentry aircraft, rocket/hyper jet or supersonic aircraft, where low density and high-temperature load-bearing capacity are critical requirements.
Like most carbides of refractory metals, zirconium carbide is substoichiometric, that is, it contains carbon vacancies. When the carbon content is higher than about ZrC0.98, the material contains free carbon. The ratio of ZrC to carbon to metal is stable in the range of 0.65 to 0.98.

How is Zirconium Carbide ZrC Powder produced?
Zirconium carbide can be manufactured in several ways. One method is the carbothermal reaction of zirconia and graphite. The result is powder. The dense ZrC can then be made by sintering the ZrC powder at a temperature higher than 2000°C. Hot pressing of ZrC can lower the sintering temperature, thus helping to produce fine particles of completely dense ZrC. Spark plasma sintering has also been used to produce fully dense ZrC.
Zirconium carbide can also be manufactured by solution-based processing. This is achieved by refluxing the metal oxide and acetylacetone.
Another manufacturing method is chemical vapor deposition. This can be achieved by heating the zirconium sponge and decomposing the halide gas.
The poor oxidation resistance above 800°C limits the application of ZrC. One way to improve the oxidation resistance of ZrC is to prepare composite materials. The important composite materials proposed are ZrC-ZrB2 and ZrC-ZrB2-SiC composite materials. These composite materials can work at temperatures up to 1800°C. Another way to improve this situation is to use another material as a barrier layer, such as in TRISO fuel particles.
Applications of Zirconium Carbide ZrC Powder:
Zirconium carbide is a kind of high melting point material with high hardness and excellent high temperature refractory. Used as a material for solid propellant in rocket engines.Used in the production of alloy steel. It is also a raw material for the production of zirconium and zirconium tetrachloride, as well as promising fine ceramic materials. Zirconium carbide used as an incandescent filament. Now it is mainly used as abrasive. It can also be used as raw materials for cemented carbide.
As a hard refractory ceramic material, zirconium carbide is commonly used in cutting tool heads. By sintering, zirconium carbide (ZRC) has high-temperature oxidation resistance, high strength, high hardness, good thermal conductivity and toughness. In addition, zirconium carbide (ZrC) nanopowders have a high visible light absorption rate, excellent infrared reflectance and large energy storage properties.
Coating material
ZrC-free and niobium carbide are used as refractory coatings in nuclear reactors. It has a low neutron absorption cross-section and is less sensitive to damage under radiation. It can be used as a coating for uranium dioxide and OR dioxide particles in nuclear fuel. Coatings are usually deposited by superheated chemical vapor deposition in a fluidized bed reactor. It also has a high emissivity and high current capacity at high temperatures, making it a promising material for thermo-photoelectric radiators, field emitter tips and arrays.
The cementing tools
Because of their hardness, cemented carbide compounds can be used for drills and other tools that require wear resistance. Zirconium carbide (ZrC) is an important high-temperature structural material with a high melting point, high strength and corrosion resistance. The application of cemented carbide can improve the strength and corrosion resistance of the material.
Nanostructured parts
Zirconium carbide nanoparticles can be used in the metallurgical, chemical, and aerospace industries in nanostructured parts. It can be used in the textile industry to manufacture nylon, fiber and carbide thermostatic textiles. Composites used in ceramic and metal substrates are also made from these nanoparticles.
