Silicon nitride ceramics are high-performance advanced ceramic materials offering excellent mechanical strength, high-temperature resistance, corrosion resistance, and wear resistance, combined with superior thermal shock stability and a low coefficient of thermal expansion (CTE).
InnoTech offers silicon nitride ceramics produced via multiple processes, including Reaction Bonded Silicon Nitride (RBSN), Hot Pressed Silicon Nitride (HPSN), and Gas Pressure Sintered Silicon Nitride (GPSN), serving machinery, electronics, chemical, and energy industries.
Silicon nitride substrates are high-performance ceramic substrates featuring high thermal conductivity, high strength, high hardness, high resistivity, excellent thermal shock resistance, low dielectric loss, and a low CTE.
Active Metal Brazing (AMB) forms a chemical bond between the ceramic and metal layers through a high-temperature brazing process in which active metals react with the ceramic surface. AMB silicon nitride substrates combine high thermal conductivity, high strength, and excellent CTE matching with high current-carrying capacity, high integration, and outstanding reliability. Chemical etching enables complex circuit designs on AMB ceramic substrates, simplifying the package structure.
Low CTE, high thermal conductivity, high strength and toughness, high surface precision, plasma corrosion resistance more than three times that of alumina, service life exceeding 50,000 hours, and excellent chemical stability.
Silicon nitride bearings and bearing balls are precision ceramics sintered at high temperature in a non-oxidizing atmosphere. They feature low density, high strength, superior wear and corrosion resistance, high-temperature stability, electrical insulation, and non-magnetic properties, operating reliably under extreme conditions including high and low temperatures, vacuum, and corrosive environments.
Silicon nitride ceramic valves, pumps, and seals are industrial components designed for high-temperature, high-pressure, and highly corrosive and abrasive environments.
Silicon nitride ceramics offer high hardness, wear resistance, corrosion resistance, high-temperature stability, and excellent chemical stability, making them ideal for premium grinding media and mill liners. Compared to zirconia, Si₃N₄ exhibits an order-of-magnitude lower wear rate, delivering extended service life and minimal contamination—essential for maintaining the purity of ultra-high-purity materials.
