Pressureless Sintered Silicon Carbide (SSiC) mechanical Seal Rings

Mechanical Seal Rings,which used in Mechanical Seal ,is made of Pressureless Sintered Silicon Carbide (SSiC). Sintered with sub-micron ultra-fine high purity silicon carbide material at 2100 °C -2150 °C high temperature. With high strength ,hardness and excellent corrosion resistance, the material is the most excellent corrosion material among the existing engineering ceramics. It can be prolonged used in an oxidizing atmosphere at 1600 °C. Excellent thermal shock resistance.
