Overview of Zirconium Carbide ZrC Powder:

Zirconium carbide (ZrC) ceramic material with a high melting point, high hardness, excellent mechanical properties, and high conductive (hot) rate and excellent antioxidant ablation performance, as one of ultra high-temperature ceramic material system, can be used as heat materials applied in spaceflight and propulsion systems, such as the shuttle's wing leading edge, a hypersonic scramjet, etc. The lattice structure of ZrC ceramic material is a tight cubic lattice composed of Zr atoms, and C atoms are located in the octahedral gap position of the lattice. Therefore, the crystal structure of ZrC ceramic material belongs to the typical NaCl face-centered cubic structure. The ZrC lattice constant A =0.46930nm, and the atomic radius ratio of C to Zr is 0.481.

In order to prepare ZrC ceramic powders with uniform particle size and high purity, researchers at home and abroad have carried out some studies on the preparation of ZrC ceramic powders. Zirconium carbide is a kind of high melting point material with high hardness and excellent high-temperature refractory material. It is used as a feedstock for solid propellants in rocket engines. Used in the production of alloy steel. It is also a raw material for the production of metal zirconium and zirconium tetrachloride, and a promising fine ceramic material. At present, the main preparation methods of ZrC powder are electric arc furnace carbothermal reduction, self-propagating high-temperature synthesis (SHS), sol-gel method and high-energy ball milling method. The steps for preparing ZrC powder by a carbothermal reduction in an electric arc furnace are as follows:

The carbothermal reduction method of electric arc furnace is the most effective industrial preparation method at present, which takes zircon or pelagic zircon as the precursor, and then generates ZrC powder through carbothermal reduction reaction under high temperature and high pressure. The reaction mechanism is as follows:

ZrSiO4 + 4C = ZrC + 3CO↑ + SiO↑

ZrO2 + 3C = ZrC + 2CO ↑

The temperature of the arc furnace should be strictly controlled in the reaction process. If the reaction temperature is too low, less SiO will be eliminated, which will lead to the formation of ZrC powder containing more impurity phase Si and C, thus affecting the purity of ZrC powder. ZrC powders prepared by a carbothermal reduction in an electric arc furnace have a simple equipment structure and simple operation, but the cost is high and the size of ZrC powders prepared is larger. The powders of ZrC ceramics prepared by carbothermal reduction reaction have uniform particle size and the size is less than 200nm.

Application of ZrC powder of zirconium carbide:

What are the application fields of ZrC powder of zirconium carbide?

Zirconium carbide ZrC Powder particles have the characteristics of high strength, high hardness, high-temperature oxidation resistance, excellent toughness and thermal conductivity. They also have optical properties such as infrared reflectivity, high visible light absorption and the ability to store large amounts of energy. Non - hafnium zirconium carbide and niobium carbide can be used as refractory coatings for nuclear reactors. It can be used as a coating for uranium dioxide and thorium dioxide particles in nuclear fuel because of its low meson absorption cross-section and weak damage sensitivity under irradiation. Carbides are characterized by hardness; Therefore, they can be used as drills and other wear-resistant tools. Nano-zirconium carbide ZrC Powder can be used in the fields of metallurgy, chemical industry, aviation and other nanostructures. In the textile industry used in the manufacture of nylon, fiber and carbide thermostatic textiles. Zirconium carbide can also be used in ceramic and metal matrix composites also made from these nanoparticles.

Coating material

Non - hafnium zirconium carbide (ZrC) and niobium carbide can be used as refractory coatings for nuclear reactors. Because of the low neutron absorption cross-section and weak sensitivity to radiation damage, it can be used as the coating of uranium dioxide and thorium dioxide particles. Coatings are usually deposited in a fluidized bed reactor by superheated chemical vapor deposition. It also has a high emissivity and high current capacity at high temperatures, making it a promising material for use in thermal photovoltaic radiators and field emitter tips and arrays.

Carbide tool

Because of their hardness, cemented carbide compounds can be used as drill bits 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 part

Nano-zirconium carbide ZrC Powder can be used in the fields of metallurgy, chemical industry, aviation and other nanostructures. It has been used in the textile industry to make thermostatic fabrics of nylon, fiber and cemented carbide. Composites used in ceramics and metal substrates are also made from these nanoparticles.
