Description of SiC seal ceramic rings

Silicon carbide is in the same family of ceramic, but SiC seal ceramic face has a much better hardness and lubrication than aluminum oxide (Alumina) ones. There are 2 types of silicon carbide, the one is directly sintered silicon carbide(SSiC), another one is reaction-bonded silicon carbide(RBSiC) .SSiC can withstand higher temperature and pressure than RBSiC.

We offer a variety of customized and standard seal ceramic face from prototyping to massive production. All these Ceramic Seal Faces are widely used in a different water pump, gas & oil production, chemical & petrochemical, refinery, power, pharmaceutical and so on.
