Silicon Nitride Structural Member
Silicon nitride (Si3N4) is an important structural ceramic material with high hardness,lubricity and wear resistance. It resists oxidation at high temperatures. Moreover, it can also resist cold and hot shocks,and is often used to manufacture mechanical components such as bearings, gas turbine blades,mechanical sealing rings and permanent moulds.Among the ceramic materials,it has the best comprehensive mechanical properties, and can be used as bearing balls, rollers, ball races, sealing materials, etc.
Application:
1.GBT ceramic substrate heat sink
2. Insulation column
3. Ceramic bearings
