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.
