silicon carbide ceramics are extraordinarily hard, wear-resistant and possess
excellent thermal conductivity properties. Corrosion, abrasion or erosion by
liquid media . as is wear due to friction.
What's more, this material can also be used in the food and beverage industry
because silicon carbide is non-toxic.

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 ℃ 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.
