Ukuze kuvinjelwe umonakalo wokugqwala obangelwa ukugqwala kwe-flake graphite ekushiseni okuphezulu, kuyadingeka ukuthola into yokufaka ijazi ezintweni ezishisa kakhulu, ezingavikela ngempumelelo i-flake graphite ekugqwaleni ekushiseni okuphezulu. Ukuze sithole lolu hlobo lwejazi lokulwa nokugqwala kwe-flake graphite, kumele kuqala sibe nezici ezithile ezifana nokumelana nokushisa okuphezulu, ukuqina okuhle, ukusebenza okuhle kokulwa nokugqwala, ikhono eliqinile lokulwa nokugqwala kanye nobunzima obukhulu. Abahleli be-graphite abalandelayo be-Furuite babelana ngezindlela zokuvimbelai-graphite ye-flakeekufakweni kwe-oxidized ekushiseni okuphezulu:
1. Sebenzisa izinto ezinomfutho womusi ongaphansi kuka-0.1333MPa(1650℃) kanye nezakhiwo ezinhle eziphelele.
2. Khetha izinto zesigaba sengilazi ezihlangabezana nezidingo zokusebenza njengento ezivala yona, bese uzenza zibe izinto zokuvala eziqhekekile ekushiseni okusebenzayo.
3. Ngokusho komsebenzi wamandla akhululekile ajwayelekile wokusabela nomoya-mpilo kanye nokushisa, ekushiseni kokwenza insimbi (1650-1750℃), izinto ezihambisana nomoya-mpilo kakhulu kune-carbon-oxygen zikhethwa ukuze zithathe umoya-mpilo kuqala, ukuze zizixube futhi zivikelei-graphite ye-flakeUmthamo wesigaba esisha esikhiqizwa ngemva kokukhishwa kwe-oxidation mkhulu kunowesigaba sokuqala, okuwusizo ekuvimbeleni isiteshi sokusabalalisa umoya-mpilo ngaphakathi futhi kwakhiwe isithiyo sokukhishwa kwe-oxidation.
4. Ekushiseni okusebenzayo, inani elikhulu lezinto ezifakiwe njenge-Al2O3, i-SiO2 kanye ne-Fe2O3 ensimbini encibilikisiwe zingamuncwa, ezisabela ngokwazo ku-sinter, ukuze izinto ezihlukahlukene ezifakiwe ezivela ensimbini encibilikisiwe zingene kancane kancane embozweni.
I-graphite ye-Furuite isikhumbuza ukuthi izinga lokushisa le-oxidation le-flake graphite ezindaweni ezikhiqiza kakhulu zaseShayina lingu-560815℃ lapho okuqukethwe kwekhabhoni kungu-88%96% kanti usayizi wezinhlayiya ungaphezu kwe-mesh engu--400. Phakathi kwazo, lapho usayizi wezinhlayiya ze-graphite ungu-0.0970.105mm, izinga lokushisa le-oxidation le-graphite elinokuqukethwe kwekhabhoni okungaphezu kuka-90% lingu-600815℃ kanti ele-graphite elinokuqukethwe kwekhabhoni okungaphansi kuka-90% lingu-62075℃. Okucwebezelayo kakhului-graphite ye-flakeKulapho izinga lokushisa eliphakeme le-oxidation liphakama khona, futhi lapho ukulahlekelwa kwesisindo se-oxidation kuyancipha khona lapho izinga lokushisa eliphezulu liphakama.
