Reaction-bonded Silicon Carbide- RBSIC(SiSiC)
This is reaction-bonded (silicon infiltrated) silicon carbide, being formed zero porosity by filling up open porosity with silicon metal (Si). Because of it's zero porosity characteristic, thermal conductivity is more than twice of Oxide Bonded SiC's, bending strength is more than 5 times higher comparing to Oxide Bonded SiC. RBSIC(SiSiC)'s special feature is its ability to maintain high strength from room temperature up to 1,350°C. Also it has very high oxidation resistance, chemical resistance and wear resistance. Used as beam, roller, radiant tube burner and burner nozzle etc.
