Impuphu ye-graphite inezindlela eziningi zokusebenzisa, njengezitsha ezibunjiwe nezingaphili ezenziwe ngempuphu ye-graphite kanye nemikhiqizo ehlobene nayo, njengezitsha ezivuthayo, i-flask, izitophu kanye nama-nozzles. Impuphu ye-graphite inokumelana nomlilo, ukwanda okuphansi kokushisa, ukuqina lapho ingena futhi igezwa yinsimbi enqubweni yokuncibilikisa insimbi, ukuqina okuhle kokushaqeka kokushisa kanye nokuqhuba kahle kokushisa ekushiseni okuphezulu, ngakho-ke i-graphite powder kanye nemikhiqizo ehlobene nayo isetshenziswa kabanzi enqubweni yokuncibilikisa insimbi ngqo. Umhleli we-graphite we-Furuite olandelayo uzokwethula ngokuningiliziwe:
I-crucible yendabuko ye-graphite yobumba yenziwe nge-flake graphite equkethe ngaphezu kuka-85% wekhabhoni, ngokuvamile i-graphite flake kufanele ibe ngaphezu kwe-mesh eyi-100. Njengamanje, intuthuko ebalulekile kubuchwepheshe bokukhiqiza i-crucible kwamanye amazwe ukuthi uhlobo lwe-graphite esetshenziswayo, usayizi kanye nekhwalithi ye-flake zinokuguquguquka okukhulu; Okwesibili, i-crucible yendabuko yobumba yathathelwa indawo yi-silicon carbide graphite crucible, eyaqala ukuba khona ngokwethulwa kobuchwepheshe bokucindezela okuqhubekayo embonini yokwenza insimbi.
I-graphite ye-Furuite ingasetshenziswa futhi ku-graphite powder ngokusebenzisa ubuchwepheshe bokucindezela obuqhubekayo. Ku-clay graphite crucible, i-large flake graphite enokuqukethwe kwe-carbon okungu-90% ithatha cishe u-45%, kuyilapho ku-silicon carbide graphite crucible, okuqukethwe kwezingxenye ezinkulu ze-flake ze-graphite powder kuthatha u-30% kuphela, kanti okuqukethwe kwe-carbon kwe-graphite kwehliswa kube ngu-80%.
