Tilmaamaha budada graphite: korantada xooggan iyo kuleylka kuleylka, nadiifin sare iyo qaab dhismeedka crystalline sare, xasilloonida xooggan (molecules kaarboonka ayaa weli ah mid aan isbeddelin heerkulka sare), iyo saliidda sare.
Hexi Carbon waxa uu leeyahay waayo-aragnimo sannado badan ah soo saarista qalabka garaafyada, taasoo horseed u ah farsamaynta tignoolajiyada oo uu ka sareeyo waxqabadka qiimaha.
