Technical Parameters：

Main features: Nano-silicon nitride and ultra-fine silicon nitride powder are prepared by special process, with high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, UV reflectivity of over 95% and The absorption rate in the infrared absorption band is above 97%, the ceramic forming temperature of the device is low, the dimensional stability is good, the mechanical strength is high, the chemical corrosion resistance is good, especially the high temperature strength is large, and the self-lubricating effect is in the composite material. The formation of a fine dispersion phase greatly improves the overall performance of the composite. The product itself has self-lubricating properties and can be used in lubricating oils. High silicon nitride hardness and small sliding friction coefficient can be applied to metal surface ceramic wear-resistant composite plating. It can be used in coatings to provide wear and solvent resistance. High purity silicon nitride can be used in quartz crucible release agents.
