Barometric sintered Si3N4 silicon nitride ceramics is a kind of high performance ceramic material, which is made of silicon nitride powder by sintering process under high temperature, high pressure and no oxygen environment. Silicon nitride ceramics with high hardness, high strength, high wear resistance, high temperature stability, good corrosion resistance and other characteristics, are widely used in high temperature, high pressure, chemical corrosion and other harsh environment of mechanical parts, electronic components, thermal equipment and other fields. Compared with traditional sintered alumina ceramics, silicon nitride ceramics have higher mechanical properties and heat resistance, so it is an ideal high-performance ceramic material.
