Silicon carbide mere si quartz ájá, mmanụ ala Coke (ma ọ bụ Ịsaka), sawdust si electric aak ọkụ n'oké. Na ọdịdị e nwekwara obere sịlịkọn carbide ịnweta moissanite. Silicon carbide, makwaara dị ka Moissanite. Dịkọrọ ndụ C, N, B na ndị ọzọ na-abụghị oxide refractory ihe na elu-tech, sịlịkọn carbide bụ kasị n'ọtụtụ ebe na na ọtụtụ echekwa otu. Nwere ike na-akpọ Emery ma ọ bụ refractory ájá. Silicon carbide bụ na quartz ájá, mmanụ ala Coke (ma ọ bụ coal tar), osisi (ndụ ndụ sịlịkọn carbide mkpa dịkwuo mmepụta nke nnu) na ndị ọzọ na ngwaọrụ na elu okpomọkụ na-eguzogide ọkụ n'oké.
