The sintering method of silicon carbide/sic seal faces/rings: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.
