The features of zirconium carbide powder

2019-01-03

Zirconium carbide powder has high purity, small particle size, uniform distribution, large specific surface area, high surface activity and low bulk density.It is characterized by high temperature resistance, oxidation resistance, high strength, high hardness, good thermal conductivity and good toughness.It is an important high-temperature structural material with high melting point, high strength and corrosion resistance, and has the characteristics of high absorption of visible light, reflection of infrared ray and energy storage.
 

Application field of zirconium carbide powder:
 

Bring about nanometer zirconium carbide used in fiber: different zirconium carbide silicon carbide powder content and the way of adding the near infrared absorption properties of the fibers, when the zirconium carbide and silicon carbide fiber content is 4% (weight), near infrared absorbing properties of the fiber best, add zirconium carbide and silicon carbide fiber shell in the near infrared absorption effect is superior to add in the core layer effect.
 

The nano zirconium carbide is applied to the new thermal insulation textiles, zirconium carbide has the characteristics of highly efficient absorption of visible light and reflection of infrared.When it absorbs up to 95 percent of the short wavelength energy below two microns, the energy can be stored in the material through thermal conversion.It also has the characteristic of reflecting more than two microns infrared wavelength.The wavelength of infrared ray produced by human body is about 10 microns. When people wear clothes containing zirconium carbide nanometer, the infrared ray of human body will not be easy to emit.This shows that zirconium carbide has the ideal characteristics of heat absorption and heat storage, and can be used in new thermal insulation textiles.
 

Nano zirconium carbide is used in hard alloy, powder metallurgy, abrasive, etc. : zirconium carbide is an important high temperature structural material with high melting point, high strength and corrosion resistance.Its excellent characteristics make it has a great application space in cemented carbide.It can improve the strength and corrosion resistance of cemented carbide.
 

Nano - zirconium carbide can be used in coatings, as high - temperature coatings, improve the surface properties of materials.
 

The carbon composite functional material modifier - zirconium carbide: used to modify carbon fiber can greatly improve the strength of carbon fiber, improve fatigue resistance and wear resistance and high temperature resistance.Through the testing of modified carbon fiber, all indexes catch up with the level of foreign countries. At present, the modification of aerospace carbon fiber material is widely used, and the effect is very obvious.
