Product characteristics
Nano-silicon nitride(Si3N4) was prepared by aerosol ablation, with high purity, small particle size, uniform distribution, large surface area, high surface activity, low loose density, UV reflectivity of more than 95 % and absorption of infrared bands. The absorption rate is more than 97 %, The device has low porcelain temperature, good dimensional stability, high mechanical strength, good chemical corrosion resistance, especially high temperature strength, and has a self-lubricating effect, which forms a fine diffuse phase in the composite material. Thus, the synthetic properties of the composites are greatly improved. Its products have self-lubricating properties and can be used in lubricating oil. Silicon nitride has high hardness and small sliding friction coefficient. It can be applied to metal surface ceramics wear resistant composite plating. It can be used in coatings for wear resistance and solvent resistance. High-purity silicon nitride can be used in quartz crucible demoulding agents.
