Introduction of zirconium carbide

2017-01-16

ZrC, a gray, face-centered cubic lattice. Melting point of 3540 ℃, the theoretical density of 6.66 g / cm 3, thermal expansion coefficient of 6.7 × 10-6 ℃ -1, micro hardness of 2600kg / mm2, resistivity of 57 ~ 75 / μΩ · cm, intense oxidation temperature 1100 ~ 1400 Lt; 0 & gt; C. Do not dissolve in hydrochloric acid, but soluble in nitric acid. Powders are generally obtained by carbon reduction of ZrO2, and then through the molding, sintering and become ceramics. Can be used as electrodes, refractory crucible and cathode electron emission materials. VC silver white crystal. The density of 5.25 ~ 5.4g / cm3. Melting point 2750 ° C. Slightly harder than quartz. Vanadium pentoxide can be obtained by reduction of coke. Mainly used in the manufacture of vanadium steel.

The use of zirconium carbide powder:

1: Average particle size Laser particle size APS D50 0.8-1.5um microns Zirconium carbide powder: It is widely used in special textile materials with heat preservation and heat storage, such as denim, because of its high efficiency in absorbing visible light, reflecting infrared and energy storage. Fabrics, thermal underwear, winter sportswear, thermal pad, and so on;

2: Zirconium carbide powder can be applied to new carbon composite functional materials, can improve the high temperature corrosion resistance of its products, and now basically used in military and aviation fields;

3: Zirconium carbide powder can also be applied to electrodes, fireproof materials;

4: Zirconium carbide powder due to have high hardness, are also often used as an abrasive
