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
