Natural flake graphiteakhoza kugawidwa mu crystalline graphite ndi cryptocrystalline graphite. Crystalline graphite, yomwe imadziwikanso kuti scaly graphite, ndi scaly komanso flaky crystalline graphite. Kukula kwakukulu, kumakwera mtengo wachuma. Mapangidwe amafuta a injini ya flake graphite ali ndi mafuta abwinoko, kufewa, kukana kutentha komanso kuwongolera magetsi kuposa ma graphite ena, ndipo amapangidwa makamaka ndi zinthu zoyera kwambiri za graphite. Mkonzi wotsatira wa Furuite Graphite akuyambitsa mankhwala abwino kwambiri a fine flake graphite:
Flake graphite ndi yofanana ndi flake, yopyapyala ngati kristalographite, ndi kukula kwa (1.0 ~ 2.0) × (0.5 ~ 1.0) mm, makulidwe a 4 ~ 5 mm ndi makulidwe a 0.02 ~ 0.05 mm. Ambiri aiwo amafalitsidwa ndipo amagawika ngati hemp m'miyala, yokhala ndi dongosolo lodziwikiratu, lomwe limagwirizana ndi momwe ndege yoyalapo imayendera. Zomwe zili mu flake graphite nthawi zambiri zimakhala 3% ~ 10%, ndi kutalika kwa 20%. Nthawi zambiri zimagwirizanitsidwa ndi mchere monga Shi Ying, feldspar ndi diopside m'miyala yakale ya metamorphic (schist ndi gneiss), ndipo imatha kuwonekanso m'dera lolumikizana pakati pa miyala yamoto ndi miyala yamchere. Scaly graphite ili ndi mawonekedwe osanjikiza, ndipo kukhathamiritsa kwake, kusinthasintha, kukana kutentha ndi madulidwe amagetsi ndiabwino kuposa ma graphite ena. Amagwiritsidwa ntchito makamaka ngati zopangira zopangira zinthu zoyera za graphite.
Malingana ndi zomwe zili mkati mwa carbon, flake graphite ikhoza kugawidwa m'magulu anayi: graphite yapamwamba, high carbongraphite, sing'anga carbon graphite ndi low carbon graphite. Mkulu chiyero graphite zimagwiritsa ntchito monga kusinthasintha graphite kusindikiza zakuthupi m'malo platinamu crucible kwa mankhwala reagent kusungunuka ndi lubricant m'munsi zakuthupi. Mkulu carbon graphite zimagwiritsa ntchito refractories, lubricant m'munsi zipangizo, burashi zopangira, magetsi mpweya mankhwala, batire zopangira ndi zina zotero. Sing'anga mpweya graphite zimagwiritsa ntchito crucibles, refractories, kuponyera zipangizo, kuponyera zokutira, pensulo zopangira, batire zopangira ndi mafuta. Low carbon graphite amagwiritsidwa ntchito makamaka poponya zokutira.
