Sic mechanical seal rings or faces

Products Mode: Silicon carbide/sic mechanical seal faces/rings
Attributes
silicon carbide seal ring: as a mechanical stationary seal ring
silicon carbide seal face: as a mechanical rotary seal face
sic seal faces: as mechanical rotary seal faces
The sintering method of reaction-bonded silicon carbide mechanical seal face/ring is that silicon carbide powder with a certain amount of C is sintered in a vacumme furnace in a very high temperature.wherer the element C and S act to formulate Sic with 8% free Si, which is easy to oxide so the reaction bonded silicon carbide seal faces/rings cannot resist very strong acids and alkali, compared to ssc/s-sic/alpha sic.

The sintering method of pressureless sintered silicon carbide seal rings/faces is that silicon carbide powder with a certain amount of B and C is sintered in a vacumme furnace in a high temperature where B is dissolved into sic to lower the cristal boundary energy and C can remove SO2 to improve the surface energy.Compared to reaction bonded silicon carbide seal faces/rings, they are better in the resistance to corrosion in the extremely strong acids and alkali.
