Silicon Nitride Ceramic Ring (Inc-sn1604)

We are a reputed name in this industry as a Exporter & Manufacturer of Silicon Nitride Ceramic Ring (INC-SN1604) in Xiamen, Fujian, China.
Key Silicon Nitride (Si3N4) Characteristics:
1.corrosion resistance---used in the acid and alkali.
2.High temperature resistant,---used in 1100 a high temperature environments.
3.Non-magnetic, electrical insulation, low thermal conductivity--- used for thermal insulation material
4.Low density (3.20g / cm3), light weight, strength and hardness---used as wear-resistant materials.
5.low coefficient of thermal expansion (3.2 A 10-6 / K)(30% of alumina ceramics,less than 40% of zirconia ceramics---withstand dramatic changes of temperature.
6.Self-lubricating, low friction coefficient
