Silicon Nitride Ceramic Substrate (Si3N4)

Silicon Nitride Ceramic Substrate

Silicon Nitride (Si3N4) has very high strength, especially for hot-pressed silicon nitride, one of the world's hardest substances. It is exceptionally resistant to high temperatures, and the strength can be maintained to a high temperature of 1200 °C without falling until 1900 °C, it will decompose. We produce the Si3N4 substrates by Hot pressing.
