Si3N4 Ceramic Welding Pins Perfect Thermal Conductivity For High Temperature Application

Silicon Nitride Ceramic Tube with formula Si3N4 for Industrial Ceramic

1 . Descriptions:

Silicon nitride is an extremely efficient material for temperature measurement and control of aluminum and many nonferrous alloys. Silicon Nitride Thermocouple Protection Tubes exhibit excellent performance under corrosive and abrasive conditions and very high temperatures.

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 1200℃; 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.
