Impapuro zishushanyije nimpapuro zidasanzwe zakozwe na grafite. Iyo grafite yacukuwe mu butaka gusa, yari imeze nk'iminzani, kandi yitwa grafite karemano. Ubu bwoko bwa grafite bugomba kuvurwa no gutunganywa mbere yuko bukoreshwa. Ubwa mbere, grafite karemano yashizwe mumuti ivanze ya acide sulfurike yibanze hamwe na acide nitricike yibanze mugihe runaka, hanyuma ukakaraba namazi meza kandi urambiwe, hanyuma ugashyirwa mumatanura yubushyuhe bwo hejuru kugirango utwike. Ubwanditsi bukurikira bwa Furuite bwerekana ibyateganijwe kubyaraimpapuro:
Kuberako guhuzagurika hagati ya grafite bigenda byihuta nyuma yo gushyuha, mugihe kimwe, ingano ya grafite yaguka byihuse inshuro mirongo cyangwa amagana, bityo haboneka ubwoko bwagutse bwa grafite, bwitwa "grafite yabyimbye". Hariho ibyobo byinshi mubyimbaigishushanyo(hasigaye nyuma yo gukuramo) Kuberako hariho imyenge myinshi ifite ubunini butandukanye hamwe na scraggy, birashobora guhuzwa hamwe na crisscross hamwe nimbaraga zo hanze, aribwo kwizirika kuri grafite yagutse. Ukurikije uku kwifata kwa grafite yagutse, irashobora gutunganywa mu mpapuro.
Kubwibyo rero, icyangombwa kugirango habeho impapuro za grafite ni ukugira ibikoresho byuzuye, ni ukuvuga igikoresho cyo gutegura grafite yagutse iva mu gushiramo, gusukura no gutwika, harimo amazi n’umuriro, bishobora gutera guturika, bityo umusaruro utekanye ni ngombwa cyane; Icya kabiri, imashini zipapura hamwe nizimashini zikanda, umuvuduko wumurongo wo gukanda uruziga ntugomba kuba hejuru cyane, bitabaye ibyo bizagira ingaruka kumbaraga nimbaraga zimpapuro za grafite, kandi umuvuduko wumurongo ni muto cyane, bikaba bidashoboka cyane. Kubwibyo, inzira yimikorere igomba kuba yuzuye, kandiigishushanyoe impapuro zitinya ubushuhe. Impapuro zuzuye zigomba kuba zipakiye neza, wibuke kuba zidafite amazi kandi zikabikwa neza.
