Na u khathetse ke ho lula u fetohalithupanakong ea ho qhibiliha? Sheba phetohelo ea ronagraphite carbon crucibles! Tsenalithupali entsoe ka lisebelisoa tse phahameng tsa conductivity tsa mocheso le ts'ebetso e tsoetseng pele ea ho bōptjoa ha isostatic, e nang le sebopeho se teteaneng le se ts'oanang le mocheso o potlakileng oa mocheso. Sena se bolela hore crucible ea hau ha e tšoarelle nako e telele feela, empa hape o boloka litšenyehelo tsa matla ka lebaka la bokhoni ba eona ba ho futhumatsa hantle.
Ha ho bapisoa le li-crucibles tse tloaelehileng tsa letsopa tsa graphite, li-crucible tsa rona tsa carbon graphite li ka eketsa bophelo ba tšebeletso ea thepa e tšoanang ka makhetlo a 2-5. Ke 'nete, re lumelise liphetoho tse etsahalang khafetsa nakong ea ts'ebetso 'me u lumelise tlhahiso e phahameng le ho boloka litšenyehelo. Khetho ea thepa le khatello e phahameng ea khatello e li etsa hore li be matla hape li khone ho mamella mocheso ho fihla ho 1700°C, ha e ntse e e-na le khanyetso e ke keng ea lekanngoa le ketso ea 'mele le ea lik'hemik'hale ea ho qhibiliha.
Hase feela hore li-crucible tsa rona tsa letsopa tsa graphite li phahame ka bongata, empa lihlahisoa tsa tsona tse tsoetseng pele li etselitsoe ho hanyetsa litšila tse kotsi le oxidation eo hangata e kopanang le eona nakong ea ho qhibiliha ha tšepe. Alisa slag e khomarelang 'me u lumelise mokhoa o hloekileng, o sebetsang haholoanyane. Mokhoa o tsoetseng pele oa anti-oxidation o boetse o tiisa hore graphite e ka har'a crucible e sirelelitsoe hantle, horeho bolela ho fokotsa litšila le ho boloka chelete e ngata.
Ho tlatselletsoa ho design le tsa haotlhokeho, li-crucible tsa rona tsa graphite li na le molemo o eketsehileng oa ho boloka tikoloho. Ka khanyetso e phahameng ea oxidation le resistivity e nepahetseng, ho futhumatsa ka induction ho ka fokotsa haholo tahlehelo ea matla a sebetsang, ho boloka litšenyehelo tsa matla le ho fokotsa tšilafalo ea litšila. Li-crucibles tsa rona li na le hoo e ka bang ha ho na litšila tse kotsi, tse sa bolokeng tšepe feela, empa hape li sireletsa tikoloho.
Ka kakaretso, li-crucible tsa rona tsa graphite carbon crucibles, carbon graphite crucibles, clay graphite crucibles le li-graphite crucibles tse akaretsang li fana ka meralo ea phetoho le melemo e mengata ea ho ntlafatsa ts'ebetso ea hau ea ho qhibiliha. Li matla 'me li na le khanyetso e babatsehang ea litšusumetso tsa' mele le lik'hemik'hale tsa ho qhibiliha. Li boetse li na le tikoloho, li etsa hore e be tse phethahetseng bakeng sa ba ananelang ho tšoarella. Khetha lisebelisoa tsa rona tsa graphite carbon crucibles bakeng sa ts'ebetso e phahameng, tharollo ea moruo le e tsitsitseng.
