Impapuro zishushanyije nimpapuro zidasanzwe zitunganijwe kuva grafite nkibikoresho fatizo. Iyo grafite yacukuwe mu butaka gusa, yari imeze nk'iminzani, kandi yari yoroshye kandi yitwa grafite karemano. Iyi grafite igomba gutunganywa no gutunganywa kugirango ibe ingirakamaro. Banza, shyira grafite karemano muruvange rwa acide sulfurike yibanze hamwe na acide nitricike yibanze mugihe runaka, hanyuma uyisohokemo, uyogeshe amazi, uyumishe, hanyuma uyishyire mumatanura yubushyuhe bwo hejuru kugirango utwike. Ubwanditsi bukurikira bwa Furuite bwerekana ibyangombwa kugirango habeho impapuro za grafite:
Kuberako imirongo iri hagati ya grafite ihinduka vuba nyuma yo gushyuha, kandi mugihe kimwe, ingano ya grafite yaguka byihuse inshuro icumi cyangwa se amagana, bityo haboneka ubwoko bwagutse bwa grafite, bwitwa "kwagura grafite". Hano hari imyenge myinshi (isigaye nyuma yo gukuramo inlays) muri grafite yagutse, igabanya cyane ubwinshi bwikigereranyo cya grafite, ni 0.01-0.059 / cm3, urumuri muburemere kandi rwiza mugukwirakwiza ubushyuhe. Kuberako hariho ibyobo byinshi, ubunini butandukanye, hamwe nuburinganire, birashobora guhuzagurika hamwe mugihe imbaraga zo hanze zashyizwe mubikorwa. Nukwiyunga-kwaguka kwagutse. Ukurikije kwifata-kwaguka kwagutse, birashobora gutunganywa mubipapuro.
Kubwibyo, icyangombwa kugirango habeho impapuro za grafite ni ukugira ibikoresho byuzuye, ni ukuvuga igikoresho cyo gutegura grafite yagutse kuva kwibiza, gusukura, gutwika, nibindi, birimo amazi numuriro. Ni ngombwa cyane; icya kabiri ni impapuro zo gukora no gukanda imashini. Umuvuduko wumurongo wikanda ntukwiye kuba hejuru cyane, bitabaye ibyo bizagira ingaruka kumbaraga nimbaraga zimpapuro za grafite, kandi niba umuvuduko wumurongo ari muto cyane, birashoboka cyane. Kubwibyo, uburyo bwateganijwe bugomba kuba bwuzuye, kandi impapuro za grafite zitinya ubushuhe, kandi impapuro zuzuye zigomba kuba zipakiwe mubipfunyika bitarimo ubushyuhe kandi bikabikwa neza.
