Pressureless sintering Silicon Carbide Products(S-SiC)

       SSIC ceramic was made from high purity and ultra-fine silicon carbide powder with a small quantity of sintering aids. Under inert gas or vacuum atmosphere of barometric pressure, these materials were sintering under high temperature 1950~2100℃, the ceramics products with excellent mechanical properties (smooth, wear-resisting, etc.) and chemical properties (stable, strong corrosion resistance, etc.) were almost completely dense. Differed from SISIC, SSIC ceramics do not contain free silicon and metal adhesives which are vulnerable to corrosion, and it has achieved excellent performance in strong acid and alkali environment as it was formed by uniform and dense SiC. Independent and discontinuous spherical pores(50±μm) which putting on sliding interface of SSiC sealing article, can be used as fluid or storage of lubricants on the surface of sliding elements. It can promote the sliding interface to keep the fluid-flim bearing, which improves the friction performance of SSiC products.
        Extremely strong corrosion resistance and excellent frictional characteristic makes SSiC to be a wise choice of application of industrial sealing surface. It can be applied in the field of chemical processing, petroleum refining, waste water, paper and pulp, mining, nuke industry, ocean, household appliances and so on.
