Product Description

Product Description

Reaction Bonded sic is sintered by adding the free silicon (content is less than 12%) into the reaction sintering sub-micron silicon carbide powder in 1500 ºC vacuum sintering furnace. Company produces silicon carbide material with excellent stability and wear resistance under high and low temperature, high speed, half dry friction working condition. The maximum overall sealing ring can be as big as 800 mm. So it is widely used in the bearing, petroleum, chemical, motors, ships and pump valve industries.
