Silicon Carbide seals- Wear and corrosion resistance
Product Details
SiC seals are self bonded fine grained alpha type silicon carbide made by spray granulation of ultra-fine SiC powder, isostatic pressing and dry pressing, and pressureless sintering, with a density greater than 95% of the theoretical density.
The SSIC process is very suitable for producing SIC ceramic components such as seals, pipes, thin sheets, spheres, and small pieces due to its advantages of high production efficiency, high yield, and low processing volume.
The company uses its own high-purity SIC raw materials and strictly tests the various indicators of SSIC during the production process to ensure the quality of the products.
