Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, high mechanical strength, low thermal expansion, chemical resistance and thermal shock resistance. Semicorex silicon carbide Ceramics are ideal for sealing rings and bearings and we supply multiple sizes of silicon carbide rings as well as other SiC parts.
At Semicorex, we focus on providing high-quality, cost-effective Sic Ring for The Mechanical Seal, we prioritize customer satisfaction and provide cost-effective solutions. We look forward to becoming your long-term partner, delivering high-quality products and exceptional customer service.

The difference between SSiC and RBSiC:

1. Sintering process is different. RBSiC is to infiltrate free Si into silicon carbide at a low temperature, SSiC is formed by natural shrinkage at 2100 degrees.

2. SSiC have smoother surface, higher density and higher strength, for some sealings with more strict surface requirements, SSiC will be better.

3. Different used time under different PH and temperature, SSiC is longer than RBSiC

Features of Sic Ring for The Mechanical Seal

- Both the ceramic substrate and silicon carbide layer have a high thermal conductivity, and excellent heat distribution properties.
- Tighter dimensional tolerances lead to higher product yield and lower costs
- Avoid peeling off and ensure coating on all surface
High purity: made by CVD chemical vapor deposition under high temperature chlorination conditions.
Corrosion resistance: high hardness, dense surface and fine particles.
Corrosion resistance: acid, alkali, salt and organic reagents.
