Silicon carbide (SiC) bụ ihe semiconductor nwere oghere band sara mbara nke nwere ezigbo ike okpomọkụ na nkwụsi ike kemịkalụ.6H-Nna-egosi na nhazi kristal ya bụ hexagonal (6H), "N" na-egosikwa na ọ bụ ihe semiconductor ụdị N, nke a na-enwetakarị site na doping nitrogen.
Ihe mkpuchi silicon carbide nwere njirimara magburu onwe ya nke iguzogide nrụgide dị elu, iguzogide okpomọkụ dị elu, arụmọrụ ugboro ugboro, wdg. Ma e jiri ya tụnyere ngwaahịa silicon, ngwaọrụ nke ihe mkpuchi silicon kwadebere nwere ike ibelata mfu site na 80% ma belata nha ngwaọrụ site na 90%. N'ihe gbasara ụgbọ ala ike ọhụrụ, silicon carbide nwere ike inyere ụgbọ ala ike ọhụrụ aka iru ihe dị mfe ma belata mfu, ma mụbaa oke ịnya ụgbọala; N'ọhịa nke nkwukọrịta 5G, enwere ike iji ya maka imepụta akụrụngwa ndị metụtara ya; Na mmepụta ike fotovoltaic nwere ike imeziwanye arụmọrụ ntụgharị; Ọgbọ nke ụgbọ okporo ígwè nwere ike iji njirimara okpomọkụ dị elu na nrụgide dị elu ya.
