Water Pump Mechanical Seal Ring Black Silicon O Rings High
Temperature Sic Rings
Silicon carbide (SiC) is one of the hardest technical ceramics
available. Combined with its high thermal conductivity and superb
corrosion resistant properties, silicon carbide ceramics are
excellent materials for challenging application areas.
Sintered silicon carbide is engineered using non-oxide sintering
aids and high-temperature forming process in inert atmospheres.
Reaction bonding is made to infiltrate the green body to form
additional sic grains that bond with the primary ceramic. This
material is typically used to increase thermal shock resistance.
