Silicon nitride products are gradually replacing 99 ceramic alumina, silicon carbide, nitrogen carbon and other ceramic products with their superior performance (wear resistance, corrosion resistance, long life).
The company's silicon nitride products are divided into two types: air pressure sintering and reaction sintering. Air pressure sintering silicon nitride is mainly based on pipe fittings and shaped parts, and reaction sintering silicon nitride is mainly based on pipe fittings. With high quality and low price, we have cooperated with many foreign customers.
Silicon nitride ceramics have high strength, especially high-purity silicon nitride, which is one of the hardest substances in the world.
Very strong corrosion resistance, can be used in strong acids and alkalis, soluble in hydrofluoric acid but does not react with other organic acids
