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.

Introduction

Silicon nitride is an inorganic substance with the formula Si3N4. It is an important structural ceramic material, high hardness, itself has lubricity, and wear resistance, atomic crystal; Antioxidant at high temperatures. Moreover, it can also resist cold and thermal shock, heated to more than 1000 ° C in the air, sharply cooled and then sharply heated, and will not crumble.

Advantage

 

1.High performance.
2.Good insulation
3.High temperature resistance.
4.Wear resistant.
5.Long life
6.Accept to customize
7.A variety of ceramic materials to choose (Zirconia /Silicon Nitride)
