Detailed Product Description

High Temperature Heat Resistant Silicon Nitride Si3N4 Ceramic Welding Nozzles

Main Features:
A.  High strength over a wide temperature range
B.  High fracture toughness
C.  High hardness
D.  Outstanding wear resistance, both impingement and frictional modes
E.  Good thermal shock resistance
F.   Good chemical resistance

 

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.
Except for the excellent properties in thermal application, silicon nitride also has good mechanical, chemical, electrical properties. It has good strength, good flexture strength and wear resistance;it is a good performance electrical insulation ceramic material; it is corrosive against all inorganic acid, most of organic acid solutions and some of caustic soda solutions.
