Silicon Nitride (Si3N4) is a relatively costly, high-temperature, structural ceramic
used where heat resistance, hardness, and strength are a premium.
 It is very hard, and therefore can be used in high wear applications or applications requiring a fine surface polish.
Silicon Nitride is fabricated using either sintering, reaction bonding, hot pressing, or hot isostatic pressing.
The material properties resulting from these processes vary considerably.

(1)low confficient of thermal expansion ,only 1/4" of steel ball.
(2)less friction generated in the bearing as heat increases.
(3)low thermal conductivity.
(4)Long life and no need for lubrication.
(5)Anti-magnetic and resistant to corrosion by most substances
(6)light weight ,good surface finish and high temperature hardness.
It is suitable for applications where high loads,high speeds and extreme temperatures
It is mainly used in bearing which may work in harsh entironment.
