Silicon Nitride (Si3N4)

氮化硅组图.jpgSilicon Nitride (Si3N4) is solid ceramic material with black color. The most important feature is that it can keep high mechanical strength till 1200℃. At the same time, it also has excellent thermal shock resistance which suitable for applications with big temperature changes. With low wear friction and good self-lubrication, Silicon Nitride is applied for bearings or bearing balls.  


+High strength over a wide temperature range +High fracture toughness 
+Low thermal expansion and high thermal conductivity +High hardness 
+Good resistance to chemical and oxidation +Outstanding wear resistance 
+Good self-lubrication property +Good thermal shock resistance
