Corrosion Resistant Ceramics
Hexoloy® sintered silicon carbide has been successfully used in chemical processing applications for over 30 years. It has been used in a wide range of applications including:
-
Seal face and seat in mechanical seals used in pumps
-
Tubes in shell and tube heat exchangers
-
Thermowell protection tubes
-
Valve lining for handling mining slurries
-
Nozzles
-
Sparger tubes
-
Impellers for mixing
-
Raschig rings
-
Chemical reactor vessels
Hexoloy® silicon carbide products exhibit excellent corrosion resistance in contact with liquid and gaseous chemicals with a wide range of pH values. These products also offer low friction coefficients, excellent wear resistance, high strength and high thermal conductivity.
FAQ
Can sintered silicon carbide be used at high temperatures in corrosive environments?
Hexoloy® sintered silicon carbide has been successfully used in corrosive environments at temperatures up to 1,500°C. It is important to consider environmental chemistry and thermomechanical factors before designing process components with silicon carbide ceramics.
What advantages do sintered silicon carbide have over other ceramic materials in terms of chemical resistance?
