Graphite ikomeye ikoreshwa kenshi mugukora ibikoresho byicyuma na semiconductor. Kugirango ibikoresho byuma na semiconductor bigere ku isuku runaka no kugabanya ubwinshi bwumwanda, ifu ya grafite irimo karubone nyinshi hamwe n’umwanda muke. Muri iki gihe, birakenewe gukuraho umwanda kuri poro ya grafite mugihe cyo gutunganya. Abakiriya benshi ntibazi guhangana n’umwanda uri mu ifu ya grafite. Uyu munsi, Furuite Graphite Muhinduzi azavuga ku nama zo gukuraho umwanda mu ifu ya grafite mu buryo burambuye:
Mugihe dukora ifu ya grafite, dukwiye kugenzura byimazeyo ibirimo umwanda duhitamo ibikoresho fatizo, tugahitamo ibikoresho bibisi birimo ivu rike, kandi tukirinda kwiyongera kwanduye mugikorwa cyo gutunganya ifu ya grafite. Okiside yibintu byinshi byanduye bihora byangirika kandi bigahinduka ubushyuhe bwinshi, bityo bikagira isuku yifu ya grafite.
Iyo utanga ibicuruzwa rusange byashushanijwe, ubushyuhe bwibanze bwitanura bugera kuri 2300 ℃ naho ibyanduye bisigaye ni 0.1% -0.3%. Niba ubushyuhe bwibanze bwitanura buzamutse bugera kuri 2500-3000 ℃, ibirimo imyanda isigaye bizagabanuka cyane. Mugihe utanga ibicuruzwa byifu ya grafite, kokiya ya peteroli irimo ivu rike ikoreshwa nkibikoresho byo kurwanya no kubika ibintu.
Nubwo ubushyuhe bwo gushushanya bwiyongereye kuri 2800 ℃, umwanda uracyagoye kuwukuraho. Ibigo bimwe bikoresha uburyo nko kugabanya itanura ryaka no kongera ubucucike buriho kugirango ukuremo ifu ya grafite, igabanya umusaruro w itanura ryifu ya grafite kandi ikongerera ingufu. Kubwibyo, iyo ubushyuhe bwitanura ryifu ya grafite bugera kuri 1800 ℃, hashyizweho gaze isukuye, nka chlorine, freon nizindi chloride na fluoride, kandi ikomeza kongerwaho amasaha menshi nyuma yumuriro w'amashanyarazi. Ibi ni ukurinda umwanda uhumeka gukwirakwira mu ziko mu cyerekezo gitandukanye, no kwirukana gaze isigaye isukuye mu byobo byifu ya grafite mu kwinjiza azote.
