Application property :


 Silicon nitride has an excellent combination of material properties. The density is low, but it is extremely hard, and the special crystal structure gives it excellent thermal stability and high fracture toughness. Become a better choice for use under extreme conditions. Therefore, silicon nitride ceramic is the best choice for high-speed and high-precision bearings. It is also an important material for high-temperature forming, high-speed cutting tools, and high-temperature wear-resistant parts.
