Product Details

We produce silicon carbide ceramic products in pressureless sintering method, whose feature is to take comprehensive techniques that improve sintering to make sintered blanks of silicon carbide achieve the theoretical density of over 98% (the theoretical density of silicon carbide ceramics is 3.21g/cm3) and the silicon carbide content of over99%. Obtained silicon carbide ceramic sintered bodies have outstanding performance, and its strength that does not decrease in 1600oC so that it is particularly suitable for wear-resistant, corrosion-resistant and high-temperature-resistant conditions, such as gasket rings,
pump elements, grinding media, blast nozzles, bulletproof laminates etc. The product is our major product. coefficient of friction (about 0.2), having higher strength than pure graphite material, small density (1.65g/cm3), having self-lubricating properties similar to graphite materials, but better wear resistance than graphite material, suitable for mass production. Suitable for: workpieces with high requirements of resistance to dry friction such as gasket rings in machines with possible dry friction, sliding bearings of magnetic pumps or shield pump, valve opening and closing parts with high requirements of corrosion resistance etc.
