Sebakeng sa mekhoa ea indasteri,graphitegraphite silicon carbide crucible phetha karolo ea bohlokoa lits'ebetsong tse fapaneng tse kang metallurgy, foundry le laboratories ea lik'hemik'hale. Ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele ba lisebelisoa tsena tsa bohlokoa, ho tlameha ho lateloe mofuta o felletseng oa tlhokomelo.
Pele ho tsohle, ho boloka graphitegraphite silicon carbide crucible e hloka tlhokomelo e hlokolosi. Tsenagraphite silicon carbide crucible e tlameha ho bolokoa sebakeng se ommeng le ho sireletsoa mongobo ka linako tsohle. Ho khothalletsoa ho li boloka ka foreimi e omileng kapa ea lepolanka ho fana ka tšireletso e eketsehileng. Fragility ke tšobotsi e hlalosang ea graphitegraphite silicon carbide crucible 'me ka hona e lokela ho tšoaroa ka tlhokomelo e feteletseng nakong ea lipalangoang. Mofuta ofe kapa ofe oa tšusumetso kapa ho sisinyeha o lokela ho qojoa ka thata ho thibela tšenyo.
crucible e lokela ho futhumatsoa butle-butle ho 500°C pele o sebelisoa. Ha o eketsa lisebelisoa tsa ho futhumatsa, ke habohlokoa ho nahana ka matla a crucible le ho netefatsa hore chelete e kenyelletsoeng e pakeng tsa karolo ea boraro le tse peli ho tse tharo tsa kakaretso ea eona. Ntle le moo, lisebelisoa le li-clamp tse sebelisoang bakeng sa ho laolla li lokela ho etsoa ho latela sebopeho sa crucible 'me li be le matla a ho thibela ho thibela tšenyo leha e le efe.
Nakong ea ts'ebetso ea ho eketsa lisebelisoa, ke habohlokoa ho laola palo ea lintho tse qhibilihisitsoeng ka har'a crucible le ho qoba ho tlatsa kapa ho tiisa ho feta ho thibela ho atolosa. Ha u tlosa slag le coke marakong a ka hare le a ka ntle a crucible, ho kgothaletswa ho tlanya hanyenyane ho thibela tšenyo. Ho beoa ka nepo ka har'a sebōpi ho boetse ho bohlokoa, ka crucible e bolokiloe sebakeng se loketseng ho tloha marakong a sebōpi 'me e behoa bohareng bakeng sa ts'ebetso e nepahetseng.

Leha ho le joalo, palo e feteletseng ea li-accelerator tsa mollo le li-additives li lokela ho qojoa kaha li ka fokotsa haholo bophelo ba tšebeletso ea crucible. E le ho eketsa bophelo ba tšebeletso ea crucible, ho kgothaletswa ho e potoloha hang ka beke nakong ea tšebeliso.
Ho feta moo, ho bohlokoa ho qoba ente e tobileng ea malakabe a matla a oxidizing mahlakoreng le tlase ho crucible kaha sena se ka baka tšenyo. Ka ho latela litataiso tsena tsa tlhokomelo, lisebelisoa tsa indasteri li ka netefatsa bophelo bo bolelele le katleho ea graphite ea bonagraphite silicon carbide crucible, qetellong e kenya letsoho ts'ebetsong e bonolo ea mekhoa le lits'ebetso tse fapaneng.
