Sintered silicon carbide bush. SSIC RBSIC bush tube manufacturers and suppliers in China

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.
