Noneho ku isoko, amakaramu menshi yamakaramu akozwe muri flake grafite, none kuki flake grafite ishobora gukoreshwa nkikaramu yamakaramu? Uyu munsi, umwanditsi wa Furuit graphite azakubwira impamvu flake grafite ishobora gukoreshwa nkikaramu yamakaramu:
Ubwa mbere, ni umukara; icya kabiri, ifite imyenda yoroshye inyerera hejuru yimpapuro igasiga ibimenyetso. Niba bigaragara munsi yikirahure kinini, ikaramu yandikishijwe intoki igizwe nubunini bwiza bwa grafite.
Atome ya karubone imbere ya flake grafite itondekanye mubice, guhuza hagati yabyo ni ntege nke cyane, kandi atome eshatu za karubone murwego zirahuza cyane, kuburyo ibice byoroshye kunyerera nyuma yo guhangayika, nkigice cyo gukina amakarita, Hamwe no gusunika gato, amakarita anyerera hagati yamakarita.
Mubyukuri, icyerekezo cy'ikaramu gikozwe no kuvanga igipimo cya grafite n'ibumba muburyo runaka. Ukurikije ibipimo byigihugu, hari ubwoko 18 bwamakaramu ukurikije ubunini bwa flake grafite. “H” bisobanura ibumba kandi rikoreshwa mu kwerekana ubukana bw'ikaramu. Umubare munini imbere ya “H”, niko ikaramu ikaramu ikomera, ni ukuvuga, umubare munini wibumba rivanze na grafite mu ikaramu y’ikaramu, ntibigaragara neza inyuguti zanditse, kandi akenshi zikoreshwa mu kwandukura.
