E le ho thibela tshenyo ya mafome e bakwang ke oxidation ya graphite ya flake mochesong o phahameng, ho hlokahala hore ho fumanwe thepa ya ho roka seaparo hodima thepa ya mocheso o phahameng, e ka sireletsang graphite ya flake ka katleho ho oxidation mochesong o phahameng. Ho fumana mofuta ona wa seaparo sa anti-oxidation sa graphite ya flake, re tlameha ho qala ka ho hanela mocheso o phahameng le ho ba thata.
Ho hanyetsa mafome hantle, ho hanyetsa ho matla ha oxidation, ho thatafala ho hoholo le litšobotsi tse ling. Furuite Graphite Xiaobian e latelang e hlahisa mekhoa ea ho thibela graphite ea flake hore e se ke ea silafatsoa mochesong o phahameng:
1. Sebelisa thepa e nang le khatello ea mouoane e ka tlase ho 0.1333MPa(1650*C) le ts'ebetso e ntle e felletseng.
2. Khetha thepa ea mohato oa khalase e fihlelang litlhoko tsa ts'ebetso e le thepa e itlamang, 'me u e etse hore e be thepa ea ho koala mapetso mochesong oa mosebetsi.
3. Ho ya ka mosebetsi wa matla a tloaelehileng a mahala a karabelo le oksijene le mocheso, mochesong wa ho etsa tshepe (1650-1750*C), thepa e nang le kamano e kgolo le oksijene ho feta carbon-oxygen e kgethwa ho hapa oksijene ka ho kgetheha, e le hore e ikgodise le ho sireletsa graphite ya flake. Kamora ho kgodisetswa, mohato o motjha o nang le karolelano ya bophahamo ba mohato wa pele o a hlahiswa.
E kgolo, e thusang ho thibela mokero wa ka hare wa oksijene le ho etsa mokoallo wa oxidation.
4. Mochesong o sebetsang, palo e kholo ea lintho tse kenyellelitsoeng tse kang Al2O3, SiO2 le Fe2O3 ka tšepe e qhibilihisitsoeng li ka angoa, tse itšoarang ka botsona ho sinter, e le hore lintho tse fapaneng tse kenyellelitsoeng tse tsoang tšepeng e qhibilihisitsoeng li kene butle-butle ka har'a sekoahelo.
Mocheso oa oxidation oa graphite ea flake e hlahisoang Chaena ke 560815°C ha litaba tsa khabone li le 88%96% 'me boholo ba likaroloana bo feta meshes tse 400. Har'a tsona, ha boholo ba likaroloana tsa graphite e le 0.0970.105mm, mocheso oa oxidation oa graphite o nang le litaba tsa khabone tse fetang 90% ke 600815°C 'me litaba tsa khabone li ka tlase ho 90%.
Mocheso oa oxidation oa enke ke 620790 C. Ha graphite ea kristale e flake e le betere, mocheso oa tlhoro ea oxidation o phahame, 'me tahlehelo ea boima ba oxidation e fokola mochesong o phahameng.
