Hot Sale 99.8% Purity Beta Phase 3-5um Si3N4 Powder CAS 12033-89-5 Silicon Nitride Powder

Si3N4 Powder Features:

1. Si3N4 powder possesses high purity, narrow range particle size distribution, and larger specific surface area;

2. High surface activity, low bulk density, UV reflectivity is more than 95% and absorption rate of infrared band is above 97%.

3. The product itself possesses lubrication which can be used in lubricants, wear resistance, corrosion resistance, anti-oxidation in high temperature. And it can withstand the hot and cold shock. If it is heated to above 1000 °C in the air, and then rapidly cooled and followed by rapidly heated again, it will not fracture.

4. Si3N4 powder can greatly improve the comprehensive performance of the composite material if added because of the minor dispersed phase formed in the composite material.
