Graphite siliconized bụ ihe mejupụtara nke silicon carbide na-ejikọ na elu nke ihe e ji graphite mee. O nwere njirimara nke ike dị elu, ike igwe dị elu na iguzogide iyi nke silicon carbide, yana ihe ndị na-eme ka mmanụ na-amị amị na iguzogide okpomọkụ nke graphite. Ọ bụ ihe eji akpata esemokwu na ihe mkpuchi igwe zuru oke, dabara adaba maka mkpuchi igwe nke ọtụtụ mgbapụta mmiri, mgbapụta mmanụ, mgbapụta kemịkalụ, na bearings nke ọtụtụ mgbapụta isi dị elu na nke dị elu. Na mgbakwunye, graphite siliconized nwere ezigbo iguzogide oxidation, iguzogide ujo okpomọkụ, obere porosity, na ụfọdụ conductivity eletriki, enwere ike iji ya dị ka ihe dị ka ihe ndị na-agbaze ígwè na tubes draft.

Ihe mejupụtara nke siliconizedGraphite bụ otu, elu ya kwekọrọ n'ime ya, a na-agbanwekwa oke nhazi nke silicon carbide na graphite. Ka ọdịnaya silicon carbide dị elu, otú ahụ ka njupụta nke ihe ahụ si ka ukwuu, otú ahụ ka ike nrụgide na-arị elu, na iguzogide ya na-amụba.
