I-graphite powder inokusetshenziswa okuhlukahlukene, okufana nama-rucibles abunjiwe kanye nama-reffercractory enziwe ngofulawa we-graphite nemikhiqizo ehlobene, njenge-crucibles, i-flask, ama-stopper kanye nama-nozzles. I-graphite powder inokumelana nomlilo, ukunwetshwa komlilo okuphansi, ukuqina lapho kuthathwa futhi kugezwa ngensimbi yensimbi yokuncibilika, ukuqina okuhle okushisayo ezindaweni zokushisa eziphakeme, ngakho-ke i-graphite powder kanye nemikhiqizo yayo ehlobene nayo isetshenziswa kakhulu kwinqubo yokuncibilikisa yensimbi. Umhleli wegrafu olandelayo uzokwazisa ngokuningiliziwe:
Ubumba lwendabuko lwendabuko lwenziwe nge-flake graphite equkethe amakhabhoni angaphezu kwama-85%, imvamisa i-flake ye-graphite kufanele ibe nkulu kune-100 mesh. Njengamanje, ukuthuthukiswa okubalulekile kobuchwepheshe bokukhiqiza okuthethelwe phesheya ukuthi uhlobo lwegrafu olusetshenzisiwe, usayizi kanye nekhwalithi ye-flake inokuguquguquka okukhulu; Okwesibili, ubumba bendabuko olubethelwa luthathelwe indawo yi-silicon Carbide graphible ebekiwe, eyaqala ukuba yokwethulwa kobuchwepheshe bengcindezi engapheli embonini yensimbi.
I-graphite ye-furuite nayo ingafakwa ku-graphite powder ngokusebenzisa ubuchwepheshe bokucindezela njalo. Ku-graphite ye-clay enobuhlakani, omkhulu we-flake onama-90% okuqukethwe kwekhabhoni cishe ama-45%, okuqukethwe yi-silicon Carbide graphite ebekiwe, okuqukethwe kwezakhi ezinkulu ze-flake ze-graphite powder kuphela ama-30%, futhi okuqukethwe yi-graphite kuncishisiwe kube ngu-80%.
