Makhalidwe okulitsa a graphite flake yokulirapo ndi osiyana ndi zinthu zina zokulitsa. Ikatenthedwa kufika kutentha kwinakwake, graphite yokulirapo imayamba kukula chifukwa cha kuwonongeka kwa zinthu zomwe zagwidwa mu lattice ya interlayer, yomwe imatchedwa kutentha koyambirira kokulirapo. Imakulira kwathunthu pa 1000℃ ndipo imafika pa voliyumu yake yayikulu. Voliyumu yokulirapo imatha kufika nthawi zoposa 200 kuposa voliyumu yoyambirira, ndipo graphite yokulirapo imatchedwa graphite yokulirapo kapena graphite worm, yomwe imasintha kuchokera ku mawonekedwe oyambira a scaly kupita ku mawonekedwe a nyongolotsi yokhala ndi density yochepa, ndikupanga gawo labwino kwambiri la kutenthetsa kutentha. Graphite yokulirapo si gwero la kaboni lokha mu dongosolo lokulitsa, komanso gawo lotenthetsera, lomwe limatha kuteteza kutentha bwino. Lili ndi makhalidwe a kutentha kochepa, kutayika pang'ono kwa utsi komanso utsi wochepa womwe umapangidwa mumoto. Ndiye kodi makhalidwe a graphite yokulirapo ndi ati pambuyo poti yatenthedwa kukhala graphite yokulirapo? Nayi mkonzi kuti afotokoze mwatsatanetsatane:
1, kukana kwamphamvu kwa kuthamanga, kusinthasintha, kusinthasintha kwa kutentha ndi kudzipaka mafuta;
2. Kukana kutentha kwambiri komanso kotsika, kukana dzimbiri komanso kukana kuwala kwa dzuwa;
3. Makhalidwe amphamvu a chivomerezi;
4. Kuthamanga kwamphamvu kwambiri;
5. Makhalidwe amphamvu oletsa ukalamba ndi kusokoneza;
6. Imatha kupirira kusungunuka ndi kulowa kwa zitsulo zosiyanasiyana;
7. Si poizoni, yopanda khansa, komanso yopanda kuwononga chilengedwe.
Kufutukuka kwa graphite yofutukuka kungachepetse kutentha kwa zinthuzo ndikupeza mphamvu yoletsa moto. Ngati graphite yofutukukayo yawonjezeredwa mwachindunji, kapangidwe ka kaboni komwe kamapangidwa pambuyo pa kuyaka sikokwanira. Chifukwa chake, popanga mafakitale, graphite yofutukuka iyenera kuwonjezeredwa, yomwe imakhala ndi mphamvu yabwino yoletsa moto ikasinthidwa kukhala graphite yofutukuka ikatenthedwa.
