Green silicon carbide powder ndi chinthu chapamwamba kwambiri chomwe chimagwiritsidwa ntchito pazinthu zosiyanasiyana monga kupukuta ndi kupukuta mchenga.Amadziwika ndi kuuma kwake kwabwino kwambiri, luso lodula modabwitsa, komanso mphamvu zake zapamwamba.Green silicon carbide imapangidwa potenthetsa chisakanizo cha mchenga wa silika ndi carbon ku kutentha kwakukulu mu ng'anjo yamagetsi.Chotsatira chake ndi chinthu cha crystalline chokhala ndi mtundu wokongola wobiriwira.
