Characteristics: High purity, small particle size, uniform distribution, large specific surface area, high surface activity, low loose density, high temperature resistance, oxidation resistance, high strength, high hardness, good thermal conductivity, good toughness, small thermal neutron absorption cross-section, good radiation resistance. It is an important high-temperature structural material with high melting point, high strength, and corrosion resistance, which has the characteristics of efficient absorption of visible light, reflection of infrared radiation, and energy storage. High melting point, high hardness, poor chemical stability, decomposes in water, soluble in acid, insoluble in cold water and hydrochloric acid, soluble in hydrofluoric acid and hot concentrated sulfuric acid containing nitric acid or hydrogen peroxide.
Application:
1.For fibers: Different contents and addition methods of zirconium carbide and silicon carbide micro powders have an impact on the near-infrared absorption performance of fibers. When the content of zirconium carbide or silicon carbide in the fiber reaches 4% (by weight), the near-infrared absorption performance of the fiber is optimal. Adding zirconium carbide and silicon carbide to the shell layer of the fiber has a better near-infrared absorption effect than adding them to the core layer.
2.Used in new insulation and temperature control textiles: Zirconium carbide has the characteristics of efficient absorption of visible light and reflection of infrared radiation. When it absorbs short wavelength energy below 2 μ m, which accounts for 95% of sunlight, it can store the energy in the material through thermal conversion. It also has the characteristic of reflecting infrared wavelengths exceeding 2 μ m. The wavelength of infrared radiation produced by the human body is about 10 μ m. When people wear textile clothes containing nano zirconia, the infrared radiation from the human body will not be easily emitted outward. This indicates that zirconium carbide has ideal heat absorption and storage characteristics, and the product can be applied to new insulation and temperature control textiles.
3.Used for hard alloys, powder metallurgy, abrasives, etc.: Zirconia carbide is an important high-temperature structural material with high melting point, high strength, and corrosion resistance. Its excellent characteristics make it have great application space in hard alloys. It can improve the strength and corrosion resistance of hard alloys.
4.Used in coatings as a high-temperature resistant coating to improve the surface properties of materials.
5.Modifier for carbon carbon composite functional materials: Used to modify carbon fibers, it can significantly improve the strength, fatigue resistance, wear resistance, and high temperature resistance of carbon fibers. Currently widely used in the modification of aerospace carbon fiber materials, the effect is very significant.
6.High melting point materials with high hardness, excellent high-temperature refractory materials, a raw material for solid propellants, superhard tool materials, surface protection materials, new materials for coating nuclear fuel particle barrier layers, ceramic composite materials
7.Used for the production of alloy steel, zirconium metal, zirconium tetrachloride raw materials, fine ceramic materials, cutting tool materials, armor materials, wear-resistant welding rods, high-temperature resistant coatings, electrodes, cathode electron emission materials, abrasives, electronic equipment, infrared detection, refractory crucibles, etc.
