SiC seals are made of self-bonding, fine-grained α-type silicon carbide, manufactured using processes such as fine SiC powder spraying granulation, isostatic pressing and dry pressing, and pressureless sintering. Their density is greater than 95% of the theoretical density.
The SSIC process offers advantages such as high production efficiency, high yield, and small processing volume, making it ideal for producing SiC ceramic components, such as seals, pipes, sheets, spheres, and small parts.
The company uses its own high-purity SiC raw materials and rigorously tests all SSIC indicators during the production process to ensure product quality.
