Ssic mechanical seal rings or faces

Products Mode: pressureless sintered silicon carbide/ssic
alpha silicon carbide seal face: as a mechanical rotary seal face
pressureless silicon carbide seal ring: as a mechanical stationary seal ring
the sintering method of silicon carbide seal face/ring: hot pressing is silicon carbide powder(compounded and processed)is pressed axially and heated simultaneously. it is a sintering workmanship to mix high temperature and high pressure together.The performance of silicon carbide seal faces/rings is good but it is not easy to produce in a mass scale.

the sintering method of silicon carbide/sic seal:isostatic pressing is simplified as follows:at a high pressure(200 Mpa)made by the inert gases or nitrogen in a sealed container and at a high temperature(at least 1000),silicon carbide is pressed uniformly and evenly in all directions and the density of silicon carbide/sic seal faces/rings is much better with better homegeneity and performance than other methods.
