Product Description:                                                                                                                                               
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.
