Silicon Nitride Ceramics

Products Introduction:

Silicon nitride ceramics have many excellent properties such as high hardness, high strength, low coefficient of thermal expansion, low high-temperature creep, good oxidation resistance, good thermal corrosion resistance, and low friction coefficient. They are the most comprehensive structural ceramic materials. The theoretical thermal conductivity of single crystal silicon nitride can reach 400w/(m • k), which has the potential to become a high thermal conductivity main substrate. In addition, the coefficient of thermal expansion of silicon oxide matches well with semiconductor materials such as Si, SiC, and GaAs, making silicon nitride ceramics an extremely attractive high-strength and high thermal conductivity electronic device substrate material.
