Silicon carbide na-akpa àgwà dị ka dayamọnd. Ọ bụghị naanị na ọ bụ ihe seramiiki kachasị mfe, kamakwa ọ bụ ihe seramiiki kacha sie ike ma nwee ezigbo ike okpomọkụ, obere mgbasawanye okpomọkụ ma na-eguzogide asịd na lye nke ukwuu.
Site na seramiiki silicon carbide, ihe onwunwe ya na-anọgide na-adịgide ruo okpomọkụ karịrị 1,400°C. Elu modulus Young> 400 GPa na-eme ka akụkụ ya kwụsie ike nke ọma. Ihe onwunwe ndị a na-eme ka silicon carbide bụrụ ihe e ji arụ ụlọ. Silicon carbide na-achịkwa ire ere, nbibi na mbuze nke ọma dịka ọ na-eguzogide mmebi esemokwu. A na-eji ihe ndị dị na ya eme ihe na osisi kemịkalụ, igwe ihe, ihe ndị na-agbasa na ihe ndị na-ewepụta ihe ma ọ bụ dị ka ihe mkpuchi, dịka ọmụmaatụ.
"Nha dị iche iche nke SSiC (sintered silicon carbide) na SiSiC (silicon infiltrated silicon carbide) egosila onwe ha. Nke ikpeazụ dabara adaba karịsịa maka mmepụta nke nnukwu olu dị mgbagwoju anya."
Silicon carbide dị nchebe n'ụzọ dị ize ndụ ma enwere ike iji ya na ụlọ ọrụ nri. Ngwa ọzọ a na-ejikarị eme ihe maka ihe silicon carbide bụ teknụzụ mkpuchi ike nke na-eji bearing friction na mechanical seals, dịka ọmụmaatụ na pamụpu na sistemụ draịva. Ma e jiri ya tụnyere ọla, silicon carbide na-enye ohere ka ngwọta dị ọnụ ala karịa yana ndụ ngwaọrụ dị ogologo mgbe ejiri ya na mgbasa ozi ike na okpomọkụ dị elu. Seramiki silicon carbide dịkwa mma maka ojiji na ọnọdụ siri ike na ballistics, mmepụta kemịkalụ, teknụzụ ike, imepụta akwụkwọ na dị ka akụkụ sistemụ paịpụ.
Carbide silicon nke ejikọtara na mmeghachi omume, nke a makwaara dị ka silicon carbide silicon ma ọ bụ SiSiC, bụ ụdị silicon carbide nke a na-emepụta site na mmeghachi omume kemịkalụ dị n'etiti carbon ma ọ bụ graphite nwere porous silicon na-agbaze agbaze. N'ihi ihe fọdụrụ na silicon, a na-akpọkarị silicon carbide nke ejikọtara na mmeghachi omume dị ka silicon carbide silicon, ma ọ bụ mkpọmkpọ ya SiSiC.
Ọ bụrụ na e si n'ịkpụcha ntụ silicon carbide mepụta silicon carbide dị ọcha, ọ na-enwekarị obere kemịkalụ a na-akpọ ihe enyemaka sintering, nke a na-agbakwunye iji kwado usoro sintering site n'ikwe ka okpomọkụ sintering dị ala. A na-akpọkarị ụdị silicon carbide a sintered silicon carbide, ma ọ bụ mechie ya ka ọ bụrụ SSiC.
A na-enweta ntụ ntụ silicon carbide site na silicon carbide nke e mepụtara dịka akọwara n'isiokwu ahụ na silicon carbide.
