Impushana ye-graphite inokusetshenziswa okubanzi okuhlukahlukene, okufana neziphambano ezibunjiwe neziphikisayo ezenziwe ngempushana ye-graphite kanye nemikhiqizo ehlobene nayo, njengeziphambano, i-flask, izivalo namabhobho. I-graphite powder inokumelana nomlilo, ukunwetshwa okushisayo okuphansi, ukuzinza lapho ingena futhi igezwa ngensimbi ngesikhathi sokuncibilika kwensimbi, ukuqina okuhle kokushaqeka okushisayo kanye ne-conductivity enhle kakhulu yokushisa ekushiseni okuphezulu, ngakho-ke i-graphite powder kanye nemikhiqizo yayo ehlobene isetshenziswa kabanzi inqubo yokuncibilika kwensimbi ngokuqondile. Umhleli olandelayo we-Furuite graphite uzokwethula ngokuningiliziwe:
I-crucible yobumba ye-graphite yendabuko yenziwe nge-flake graphite equkethe i-carbon engaphezu kuka-85%, ngokuvamile i-graphite flake kufanele ibe nkulu kune-100 mesh. Njengamanje, ukuthuthukiswa okubalulekile kobuchwepheshe bokukhiqiza i-crucible phesheya ukuthi uhlobo lwe-graphite olusetshenzisiwe, ubukhulu kanye nekhwalithi ye-flake inokuguquguquka okukhulu; Okwesibili, i-crucible yobumba yendabuko yathathelwa indawo yi-silicon carbide graphite crucible, eyaba khona ngokusungulwa kobuchwepheshe bengcindezi eqhubekayo embonini yokwenza insimbi.
I-Furuite graphite ingasetshenziswa futhi ku-graphite powder ngokusebenzisa ubuchwepheshe bokucindezela njalo. Ku-clay graphite crucible, i-flake graphite enkulu enokuqukethwe kwekhabhoni engu-90% ibalelwa ku-45%, kuyilapho ku-silicon carbide graphite crucible, okuqukethwe kwezingxenye ezinkulu ze-flake ze-graphite powder kubalelwa ku-30% kuphela, kanti okuqukethwe kwekhabhoni yegraphite kuncishisiwe. 80%.
