Note: We can supply different size products of silicon nitride powders according to client's requirements.
Silicon nitride is an excellent high temperature high strength, low density, good corrosion resistance, wears resistance, thermal shock resistance, creep resistance, and excellent chemical stability.
Application of silicon nitride powders:
1.Silicon nitride ceramics are widely used in electronics, military industry, metallurgy, machinery, chemical industry and many other areas.
2. Silicon nitride powder commonly used in the preparation of the composite material, greatly improving the overall performance of the composites
3. Silicon nitride is also a wide band gap semiconductor, can obtain a higher doping concentration, and thus have the potential to be an excellent host material to use in microelectronics and optoelectronics.
4. Silicon Nitride is the main raw material for producing the the silicon nitride ceramics.
5. Silicon Nitride is self-lubricating material, the nano grade Si3N4 is available to use as lubricating oil additive.
SEM & XRD of silicon nitride powders:
Storage conditions:
silicon nitride powders should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
