Ho feta moo, ho se sebetse hantle ha dikeramike tsa silicon carbide tse sintered reaction-sintered ho etsa hore di lokele ho sebediswa dibakeng tse senyang. Di hanela tlhaselo ya dikhemikhale le oxidation mme di sebediswa diindastering tsa ho sebetsana le dikhemikhale, tsa tlhahiso ya metallurgical le tsa semiconductor. Dikarolo tsa RS-SiC di sebediswa ditshebetsong tse kenyeletsang dikhemikhale tse senyang, ditshipi tse qhibilihisitsweng le dikgase tse nang le mocheso o phahameng moo thepa e tlwaelehileng e ka senyehang kapa ya hloleha.
