Garaafyada flake dabiiciga ahwaxaa loo qaybin karaa garaafka crystalline iyo graphite cryptocrystalline. Garaafka kristal, oo sidoo kale loo yaqaan garaafka qolofleyda ah, waa garaafyada crystalline-ka qallafsan oo qallafsan. Miisaanka weyn, ayaa kor u kacaya qiimaha dhaqaale. Qaab dhismeedka lakabka ah ee saliidda garaafiga ee flake ayaa leh sif wanaagsan, jilicsanaan, caabbinta kulaylka iyo korantada marka loo eego garaafyada kale, waxaana inta badan laga sameeyaa alaabada garaafyada nadiifka ah ee alaabta ceeriin. Tifaftiraha soo socda ee Furuite Graphite wuxuu soo bandhigayaa sifooyinka kiimikaad ee wanaagsan ee garaafiga flake:
Garaafka caleenku waa flake-sida, caleen dhuuban sida crystallinegaraafka, oo cabbirkiisu yahay (1.0 ~ 2.0) × (0.5 ~ 1.0) mm, dhumucdiisuna tahay 4 ~ 5 mm, dhumucdiisuna tahay 0.02 ~ 0.05 mm. Intooda badan waa la faafiyay oo hemp-u eg ayaa loo qaybiyaa dhagaxyada, oo leh habayn toosan oo cad, kaas oo waafaqsan jihada diyaaradda gogosha. Waxa ku jira graphite flake guud ahaan waa 3% ~ 10%, oo leh dherer ka badan 20%. Waxaa badanaa lala xiriiriyaa macdanta sida Shi Ying, feldspar iyo diopside ee dhagaxyada metamorphic ee qadiimiga ah (schist iyo gneiss), waxaana sidoo kale lagu arki karaa aagga xiriirka ee u dhexeeya dhagaxyada igneous iyo limestone. Garaafyada qallafsan waxay leedahay qaab-dhismeed lakabaysan, iyo lubriness, dabacsanaanteeda, caabbinta kulaylka iyo korantada korantada ayaa ka fiican kuwa garaafyada kale. Waxaa inta badan loo isticmaalaa sida alaabta ceeriin samaynta alaabta graphite daahirnimo sare leh.
Marka loo eego nuxurka kaarboonka go'an, graphite flake waxaa loo qaybin karaa afar qaybood: garaafka daahirsanaanta sare, kaarboon saregaraafka, Garaafka kaarboon dhexdhexaadka ah iyo garaafka kaarboonka hooseeya. Garaafka saafiga ah ee sarreeya waxaa inta badan loo isticmaalaa sidii shaabaddii garaafyada dabacsan halkii laga isticmaali lahaa platinum crucible ee dhalaalka reagen kiimikaad iyo walxaha saldhigga saliidda. Garaafyada kaarboonka sare waxaa inta badan loo isticmaalaa refractories, alaabta saldhiga saliidda, buraashka alaabta ceeriin, alaabta carbon koronto, alaabta ceeriin baytari iyo wixii la mid ah. Garaafka kaarboonka dhexdhexaadka ah waxaa inta badan loo adeegsadaa weelasha, refractories, alaabta tuurista, dahaarka tuurista, alaabta ceeriin qalin, alaabta ceeriin baytari iyo shidaalka. Garaafiga kaarboonka ee hooseeya ayaa inta badan loo isticmaalaa daahanka tuurista.
