Feature of the silicon nitride powders:
1.Silicon nitride powders possesses high purity, narrow range particle size distribution, and larger specific surface area.
2.With high surface activity, low bulk density, UV reflectivity is more than 95% and absorption rate of infrared band is above 97%.
3.It does not dissolve in water, soluble in hydrofluoric acid.
Application:
1. Structure device: such as metallurgy, chemical industry, machinery, aviation, aerospace and energy industries to use the ball and roller bearing, sliding bearing, sleeve, valve, and a wear-resistant, high temperature, corrosion-resistant structural components required.
2. Composite materials: such as metals, ceramics and graphite composites, rubber, plastics, coatings, adhesives and other polymer-based composites.
3.The colorless, transparent self-lubricating wear-resistant nano-particle films for mobile phones, cars and other advanced surface protection also the silicon nitride powder application.
Storage condition:
Damp reunion will affect its dispersion performance and using effects,this product should be sealed in vacuum and stored in cool and dry room and it should not be exposure to air and avoided under stress.
