Sic mechanical seal rings or faces

Products Mode: silicon carbide/sic mechanical seal face/ring
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
reaction-bonded silicon carbide mechanical seal face/ring sintering method is that silicon carbide powder added by 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.

pressureless sintered silicon carbide seal face/ring sintering method is that silicon carbide powder added by 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, they are better in the resistance to corrosion in the extremely strong acids and alkali.
