Product Description
1, Carbon composite functional material modifier - zirconium carbide (ZrC) : zirconium carbide modified carbon fiber can greatly improve the strength of carbon fiber, increase the resistance to fatigue and wear resistance and high temperature resistance. At present, it is widely used in the modification of aerospace carbon fiber materials,  effecting obviously.After test,  all the indexes of modified carbon fiber surpass the foreign level.
2, Zirconium carbide (ZrC) applied in the field of new thermal insulation temperature textiles:  zirconium carbide with high efficient absorption of visible light, reflected infrared characteristic, when it absorbs 95% of the short wave energy from the sun, under 2 microns,after thermal conversion, energy can be stored in the material, it also can reflect the infrared wave lengths, which is more than 2 microns. Since the infrared wavelength produced by the human body is about 10μm, when people wear zirconium carbide modified textile clothes, the human body infrared will not be send out easily. This shows that zirconium carbide has ideal  characteristics of heat absorption and heat storage.
3, When zirconium carbide (ZrC) is used in cemented carbide, powder metallurgy and other fields, it can improve the strength of cemented carbide, corrosion resistance and other properties;
4, zirconium carbide (ZrC) can be used as modified agent in rocket, missile solid propellant.

Product Features
1. High purity, no impurity phase detected by XRD, low content of metal impurity elements detected by GDMS/ICP;
2. Concentrated particle size distribution, good sphericity, good fluidity, no tube blocking, good quality of 3D printing and thermal spraying.
