Inzira zo Gukora Ifu nziza-nziza ya SiC

Carbide ya Silicon (SiC)ni organic organique izwiho imiterere idasanzwe. Mubisanzwe bibaho SiC, izwi nka moissanite, ni gake cyane. Mu nganda,silicon karbideni Byinshi Byakozwe Muburyo Bwubukorikori.
Kuri Semicera Semiconductor, dukoresha tekinoroji igezweho yo gukoraifu nziza cyane ya SiC.

Uburyo bwacu bukubiyemo:
Uburyo bwa Acheson:Ubu buryo bwo kugabanya karbothermalike burimo kuvanga umucanga mwinshi wa quartz cyangwa amabuye ya quartz yajanjaguwe na kokiya ya peteroli, grafite, cyangwa ifu ya anthracite. Uru ruvange noneho rushyuha kubushyuhe burenze 2000 ° C ukoresheje electrode ya grafite, bikavamo synthesis ya α-SiC ifu.
Kugabanya Ubushyuhe Buke Kugabanya Carbothermal:Muguhuza ifu nziza ya silika nifu ya karubone no kuyobora reaction kuri 1500 kugeza 1800 ° C, dukora ifu ya Si-SiC hamwe nubuziranenge bwongerewe. Ubu buhanga, busa nuburyo bwa Acheson ariko ku bushyuhe bwo hasi, butanga β-SiC hamwe na kristu yihariye. Nyamara, nyuma yo gutunganya kugirango ikureho karubone isigaye na dioxyde ya silicon irakenewe.
Silicon-Carbone Igisubizo:Ubu buryo bukubiyemo gufata ifu ya silicon yicyuma hamwe nifu ya karubone kuri 1000-1400 ° C kugirango itange ifu yuzuye β-SiC. Ifu ya Si-SiC ikomeza kuba ibikoresho byingenzi byububiko bwa silicon karbide, mugihe β-SiC, hamwe nuburyo bwa diyama, nibyiza muburyo bwo gusya neza no gusya neza.
Carbide ya Silicon yerekana uburyo bubiri bwingenzi:α na β. β-SiC, hamwe na sisitemu ya cubic sisitemu, igaragaramo isura ya cubic lattice kuri silicon na karubone. Ibinyuranye, α-SiC ikubiyemo polytypes zitandukanye nka 4H, 15R, na 6H, hamwe na 6H zikoreshwa cyane mu nganda. Ubushyuhe bugira ingaruka ku gutuza kwa polytypes: β-SiC ihagaze munsi ya 1600 ° C, ariko hejuru yubushyuhe, igenda ihinduka buhoro buhoro kuri α-SiC polytypes. Kurugero, 4H-SiC ikora nka 2000 ° C, mugihe 15R na 6H polytypes bisaba ubushyuhe buri hejuru ya 2100 ° C. Ikigaragara ni uko 6H-SiC ikomeza guhagarara neza no ku bushyuhe burenga 2200 ° C.

Muri Semicera Semiconductor, twiyemeje guteza imbere ikoranabuhanga rya SiC. Ubuhanga bwacu muriSiCnibikoresho byemeza ubuziranenge bwo hejuru hamwe nibikorwa bya semiconductor yawe. Shakisha uburyo ibisubizo byacu byambere bishobora kuzamura inzira zawe nibicuruzwa.
