Product Description
Silicon nitride ceramic is an inorganic material ceramic that does not shrink when sintered. Silicon nitride is very strong,
especially hot pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density and
high temperature resistance.
Furthermore, it has good chemical stability and resistance to oxidation. As a result, silicon nitride ceramic has the best
comprehensive performance and most wide application in high temperature field.
Silicon Nitride is a chemical compound of silicon and nitrogen. It is a hard ceramic and is mostly used in high-endurance and high-temperature applications.
