Technical Description of silicon nitride powder
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%, device of low temperature, a China good dimensional stability, high mechanical strength, It has good chemical corrosion resistance, especially high temperature strength, and has self-lubrication effect, forming fine dispersion phase in the composite material, thus greatly improving the comprehensive properties of the composite material. The product itself has self-lubricating properties and can be used in lubricating oil.
Silicon nitride has the characteristics of high hardness and small sliding friction coefficient, which can be used in wear-resisting composite plating of metal surface ceramics. It can be used in coatings with wear-resisting and solvent resistance, and high purity silicon nitride can be used in quartz crucible demudging agent.
