Izinto zokushisa ze-graphite, njengamadivayisi okushisa okushisa okuphezulu, asetshenziswa kabanzi ezimbonini eziningi, okuhlanganisa i-metallurgy, i-electronics, i-semiconductors, kanye namakhemikhali. Izinto ze-graphite zinokuqhutshwa kokushisa okuhle kakhulu, ukumelana nokushisa okuphezulu, kanye nokuqina kwamakhemikhali, okuvumela ukuthi zigcine ukusebenza okuzinzile isikhathi eside, ikakhulukazi ezindaweni ezishisa kakhulu. Kodwa-ke, izinga lokushisa eliphezulu lokusebenza lezinto zokushisa ze-graphite lithonywa izici ezahlukahlukene, ngomehluko omkhulu emikhawulweni yokushisa phakathi kwezindawo zomoya neze-vacuum.
Ku-indawo yomoya, izinga lokushisa eliphezulu lezinto zokushisa ze-graphite linqunyelwe yi-oxidation. Lapho i-graphite heating element ishiswa emazingeni okushisa aphezulu, isabela nomoya-mpilo emoyeni ukuze yakhe i-carbon dioxide (CO₂) noma i-carbon monoxide (CO₂). Le nqubo ye-oxidation iholela ekuwohlokeni kwezinto kancane kancane kanye nokusebenza okuncishisiwe, ekugcineni kuthinta isikhathi sokuphila kwe-heater element. Ngokuvamile, ezimweni zomoya ezijwayelekile, izinga lokushisa eliphezulu lokusebenza lezinto zokushisa ze-graphite liseduze.3000°CUkudlula lokhu kushisa kusheshisa izinga lokushiswa kwe-oxidation, okubangela ukuwohloka okusheshayo kwezinto.
Ngokungafani nomoya, ku-indawo yokuhlanza umoya, i-oxidation icindezelwa ngempumelelo. Ku-vacuum, ukuhlushwa kwe-oxygen kucishe kube yi-zero, ngakho-ke akukho i-oxidation eyenzeka ebusweni be-graphite. Lokhu kuvumela izinto ze-graphite ukuthi zikwazi ukumelana namazinga okushisa aphezulu kakhulu. Eqinisweni, ku-vacuum, izinga lokushisa eliphezulu le-graphite lingafinyelela3500°Cnoma ngaphezulu, izinga lokushisa elingenakufinyelelwa emoyeni. Izinzuzo zezimo ze-vacuum azigcini nje ngokulawula i-oxidation kodwa futhi nasekuzinzeni okungcono kokushisa kanye nokuphila isikhathi eside. Lokhu kwenza izakhi zokushisa ze-graphite zilungele ukusetshenziswa kwezinga lokushisa eliphezulu kakhulu, njengokukhiqiza i-semiconductor kanye nezinhlelo zokushisa zokuhlola isikhala, lapho zivame ukusebenza khona ezimweni ze-vacuum ukuze zisebenzise ngokugcwele izakhiwo zazo zezinto ezibonakalayo.
Ngaphezu kwe-oxidation, amandla okushisa aphezulu e-graphite adlala indima ebalulekile ekunqumeni umkhawulo wayo wokushisa. Njengoba izinga lokushisa likhuphuka, i-lattice ye-graphite ingase ishintshe kancane, ikakhulukazi lapho amazinga okushisa edlula ibanga elithile. Lokhu kungabangela ukwanda kokushisa noma ukwakheka kwemifantu ebusweni. Lezi zinguquko ezibonakalayo azithinti nje kuphela izakhiwo ze-graphite kodwa futhi zinganciphisa ukuzinza kokushisa kwento yokushisa. Ngakho-ke, ukuqina kwe-graphite emazingeni okushisa ahlukene kuyisici esibalulekile ekunqumeni ukuthi ingasebenza ngokuphepha nangokuphumelelayo yini ezindaweni ezithile.
Endaweni yokushisa nge-vacuum, izinto zokushisa nge-graphite zingafinyelela amazinga okushisa aphezulu kakhulu ngoba akukho ukushiswa kwe-oxidation ukuze kuncishiswe izinto. Ngaphezu kwalokho, ku-vacuum, ukudluliselwa kokushisa kusebenza kahle kakhulu, njengoba i-graphite ingadlulisela ukushisa kangcono endaweni yokusebenza ngaphandle kokuphazamiseka kwe-oxidation. Lokhu kwenza izinto zokushisa nge-graphite zilungele ukusetshenziswa kuma-vacuum furnace, ukuncibilika nge-laser, izinhlelo zokushisa isikhala, kanye nezinye izinhlelo zokusebenza zokushisa okuphezulu.
Kodwa-ke, naphezu kwezinzuzo ezibalulekile zendawo yokuhlanza umoya, ezinye izici kumele zicatshangelwe lapho kusetshenziswa izinto ze-graphite ku-vacuum. Isibonelo, ukuhanjiswa kokushisa kwe-graphite kungashintsha kancane ngenxa yokushintshashintsha kwengcindezi yegesi. Ngakho-ke, ukulawulwa kokushisa kwezinto zokushisa ze-graphite ezimweni ezahlukene ze-vacuum kusadingeka kulungiswe ngokusekelwe ezimweni ezithile. Ngaphezu kwalokho, yize i-oxidation ivinjelwa ku-vacuum, izimo ezimbi kakhulu njengokukhishwa kwe-arc zingase zithinte ukuzinza nokuqina kwe-graphite.
Ngamafuphi, umehluko emikhawulweni yokushisa yeizinto zokushisa ze-graphiteezindaweni zomoya kanye ne-vacuum kukhombisa ukusebenzisana okuyinkimbinkimbi phakathi kwezakhiwo zezinto kanye nezici zemvelo. Ukugcwala kwe-oksijini emoyeni kuyisici esiyinhloko esivimbela ukuzinza kwe-graphite emazingeni okushisa aphezulu, kuyilapho indawo ye-vacuum inikeza ipulatifomu ecishe ingabi ne-oxidation, evumela i-graphite ukuthi isebenze emazingeni okushisa aphezulu kakhulu. Lapho ukhetha izinto zokushisa ze-graphite zezinhlelo ezithile, kubalulekile ukucabangela indawo yokusebenza ukuze unqume ukuthi uzosebenzisa yini umoya noma i-vacuum heating. Ukuze uthole ukushisa okuzinzile okushisa kakhulu, okuhlala isikhathi eside, izinto zokushisa ze-graphite ezindaweni ze-vacuum ngokungangabazeki zizuzisa kakhulu.
