Siliconized graphite bụ ihe ngwakọta nke silicon carbide na-ejikọta n'elu nke mkpụrụ graphite.Ọ nwere njiri mara nke ịdị elu siri ike, ike igwe dị elu ma na-eyi nguzogide nke silicon carbide, yana njirimara mmanye onwe ya na nguzogide ujo nke graphite.Ọ bụ ihe kacha mma esemokwu ihe na n'ibu akara ihe, adabara n'ibu akara nke dị iche iche mmiri nfuli, mmanụ nfuli, chemical nfuli, na bearings nke dị iche iche elu-ọsọ na elu ibu isi nfuli.Na mgbakwunye, siliconized graphite nwere ezigbo nguzogide oxidation, nguzogide ujo ọkụ, obere porosity, na ụfọdụ conductivity eletrik, enwere ike iji ya dị ka ihe ndị dị ka igwe na-agbaze ọla na tubes.
Ihe mejupụtara nke siliconizedgraphite bụ edo, elu na-adaba n'ime, yana nhazi nke silicon carbide na graphite bụ mgbanwe.Ọdịnaya nke silicon carbide dị elu, ka njupụta nke ihe ahụ na-abawanye, na-abawanye ike mkpakọ, na mgbochi na-abawanye.
