Silicon nitride 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.

Features 1.High hardness 2.Wear resistance 3.High fire  resistance 4.Corrosion preventive 5.Good chemical stability

Applications Silicon nitride is widely used in many industries such as iron and steel, non-ferrous metals, chemical building materials and so on. It has the advantages of energy saving, environmental protection, high temperature resistance, corrosion resistance and so on.
