Material Introduction:
Silicon Nitride (Si3N4) is a widely used ceramic material in high
temperature application, it has high strength in both room
temperature and high temperature condition, the strength of silicon
nitride can be kept up to 1200ºC; the low coefficient of thermal
expansion make it a ceramic material possessing excellent thermal
shock resistance; at the same time, it also has good thermal
conductivity.
