The main features of nanometer zirconium carbide, ultra-fine zirconium carbide powder prepared through a special process, the powder of high purity, small particle size distribution, specific surface area, high surface activity, bulk density, high temperature, oxidation resistance, strength high hardness, good thermal conductivity, good toughness, it is an important high melting point, high strength and corrosion resistance of high temperature structural materials, and highly efficient absorption of visible light, infrared reflection, and energy storage characteristics.
Applications
1 nanometer zirconium carbide used in fiber: zirconium carbide content of silicon carbide powder and add the fiber near infrared absorption affect the performance of zirconium carbide or silicon carbide fiber content of 4% (by weight), the near-infrared absorption of the fiber the best performance, add the zirconium carbide and silicon carbide fiber shell near-infrared absorption is better than added to the core in effect;
2 nanometer zirconium carbide used in the new insulation thermostat textiles: zirconium carbide has a high absorption of visible light, reflection infrared characteristics, when it absorbs short-wavelength energy accounted for 95 percent of the sunlight below 2μm, heat transfer can be energy stored in the material, it has the characteristics of reflection more than 2 μm infrared wavelengths. About 10μm infrared wavelength produced by the body when people wear including the Nano – of ZrC textile and clothing, the human body infrared will not easily radiated. This shows that the zirconium carbide with ideal endothermic, and heat storage characteristics of the products can be used in the new insulation thermostat textiles;
3 nanometer zirconium carbide is used in carbide, powder metallurgy, abrasives, such as: zirconium carbide is an important high melting point, high strength and corrosion-resistant high-temperature structural materials. Its excellent features in a lot of applications of space in the cemented carbide.Can improve the carbide strength, corrosion resistance, etc.;
4 nanometer zirconium carbide can be applied to the coating as a heat resistant coatings, to improve the surface properties of materials;
Modifier of the carbon-carbon composite materials – zirconium carbide (ZrC): 5 for the modified carbon fiber can significantly improve the strength of carbon fiber, to improve the fatigue resistance and wear resistance and high temperature performance. Catch up with the level of foreign modified carbon fiber have been tested, and all indications are now widely used in the aerospace carbon fiber modified, the effect is very obvious.
