Silicon nitride is a kind of widely used advanced industrial ceramic, to meet the needs of different fields, raw material composition and appropriate sintering process can be selected, and required properties are achieved.
⩟ High strength
Strength of silicon nitride is high, flexture strength is up to 900MPa, also the fracture toughness is high, so it can be used for application with heavy load and mechanical shock;
⩟ Corrosion resistance
Silicon nitride material has good corrosion resistance, it does not react with various acids, alkalis, salt or other chemical agents, without the risk of failure caused by corrosion;
⩟ High temperature resistance
The normal use temperature of the silicon nitride ceramic can reach higher than 1100℃, available for the requirements of high temperature environment;
⩟ Good wear resistance
Silicon nitride material has high hardness, which is up to 16GPa, so the wear resistance is very good and service life is long;
⩟ Good thermal shock resistance
Silicon nitride has small thermal expansion, and high termal conductivity, thermal shock resistance is very good, up to 550℃.
