Main characteristics
Ultrafine nano silicon nitride, silicon nitride powder by variable current laser ion beam, chemical vapor deposition) of high purity, small particle size, uniform distribution, specific surface area, high surface activity, low apparent density, uv reflectance for more than 95% and absorb infrared absorption rate of over 97%, the device of low temperature, a China good dimensional stability, high mechanical strength, good resistance to chemical corrosion performance, especially the high temperature strength, and has self lubricating effect, its form a fine dispersion phase in the composites, thus greatly improve the comprehensive performance of composite materials. The product itself has the self-lubricating performance, can be used lubricating oil. Silicon nitride high hardness, the characteristics of the sliding friction coefficient can be applied to the metal surface ceramic wear-resistant composite plating, applied to the coating can be resistant and solvent resistance characteristics, can be used in high purity silicon nitride quartz crucible mold release agent.
