Mu rwego rwo gukora ibyuma no gukora, guhitamo ibikoresho byingenzi bigira uruhare runini muguhitamo imikorere, ubwiza, nigiciro-cyiza cyo gushonga. Mu bikoresho bitandukanye biboneka,grafite silicon karbide (SiC) umusarabauhagarare kubintu byihariye bidasanzwe, bigatuma bahitamo guhitamo ubushyuhe bwo hejuru bwo gushonga ibyuma. Iyi ngingo irasesengura ibyiza byihariye bya grafite ya SiC ugereranije nibindi bikoresho nka grafite nziza, alumina, hamwe n’ibyuma, byerekana imikorere yabo mu nganda zitandukanye.
Ubushyuhe budasanzwe budasanzwe hamwe no kurwanya ubushyuhe
Graphite SiC ibamba ryerekana ubushyuhe butagereranywa bwumuriro no guhangana nubushyuhe bwo hejuru, bushobora kwihanganira ibidukikije bishyushye nka 1600 ° C kugeza 1650 ° C. Uku kwihanganira ubushyuhe budasanzwe ntibishobora gusa gushonga ibyuma bishonga cyane nkumuringa, zahabu, ifeza, nicyuma ahubwo binashimangira ubunyangamugayo bukomeye no kuramba mugihe cyubushyuhe bukabije. Ibinyuranyo, ibikoresho nka grafite nziza na alumina bitanga ubushyuhe buke bwumuriro, bikagabanya ubukana bwa progaramu yubushyuhe bwo hejuru.
Kurwanya Kurwanya Imiti
Imiti idahwitse ya grafite ya SiC ni iyindi nyungu ikomeye, itanga imbaraga zo guhangana nigitero cyangirika cyimiti itandukanye igira uruhare mugushonga ibyuma. Iyi ngingo iremeza ko ingenzi zidahumanya gushonga, harebwa cyane inganda aho isuku yicyuma aricyo cyambere, nko mubikorwa bya semiconductor no kubyara imirasire y'izuba. Mugihe ibishushanyo mbonera bya grafite nabyo bifite imiti irwanya imiti, ntibishobora gukora neza mubidukikije bimwe na bimwe byangirika ugereranije na grafite ya SiC.
Ubushyuhe bwo hejuru cyane bwo gushonga neza
Ubushyuhe bwo hejuru bwumuriro wa grafite SiC yorohereza gukwirakwiza ubushyuhe bwihuse kandi bumwe, nibyingenzi gushonga neza kandi bihamye. Iyi miterere igabanya cyane gukoresha ingufu nigihe cyo gushonga, byongera umusaruro rusange mubikorwa byo gushonga. Imirambararo ya grafite isangiye iyi mico yingirakamaro, ariko umusaraba wa grafite ya SiC uyihuza hamwe nubushuhe buhebuje bwumuriro, bitanga inyungu zitandukanye mugusaba porogaramu.
Porogaramu hirya no hino mu nganda
Ibintu bidasanzwe bya grafite ya grafite ya SiC ituma bikwiranye nuburyo butandukanye bwa porogaramu zirenze gushonga ibyuma. Mu nganda za semiconductor, guhangana nubushyuhe bwo hejuru no kwangirika kwimiti bituma biba byiza kubyara wafer ya silicon nibindi bikoresho bya semiconductor. Urwego rukomoka ku mirasire y'izuba kandi rwungukirwa no gukoresha umusaraba wa grafite ya SiC mu gukora silikoni isukuye cyane ku mirasire y'izuba. Byongeye kandi, kuramba no gukora neza byabagize ibikoresho byo guhitamo muri laboratoire yubushakashatsi hamwe no gukoresha ibyuma byabugenewe, aho usanga ari ngombwa kandi byizewe.
Umwanzuro
Graphite silicon carbide crucibles yerekana iterambere ryibanze muburyo bwikoranabuhanga rikomeye, ritanga imikorere isumba iy'ubushyuhe bwo hejuru, isuku ryinshi, hamwe nuburyo bwo gukora ibyuma bishonga cyane. Ubushyuhe bwabo butagereranywa, kurwanya imiti, hamwe nubushyuhe bwumuriro bituma bahitamo guhitamo mubikorwa bitandukanye byinganda nubushakashatsi, bagashyiraho ibipimo bishya byubuziranenge no gukora neza mubyuma. Mugihe inganda zikomeje gutera imbere, gukenera ibikoresho bishobora kwihanganira ibihe bikabije mugihe bitanga imikorere idasanzwe bigenda byiyongera, bigashyira umusaraba wa grafite SiC ku isonga mubikorwa byubuhanga bugezweho nibikoresho bya siyansi.
Ubu bushakashatsi ku byiza no gushyira mu bikorwa ibishushanyo mbonera bya grafite ya SiC bishimangira akamaro kabo mu nganda z’iki gihe, bitanga ubumenyi ku ruhare rwabo mu guteza imbere ikoranabuhanga mu nganda no kugira uruhare mu iterambere ry’ibicuruzwa byiza kandi byiza.
