Crucible Technical Litšobotsi Le Kopo Analysis

Li-crucibles ke lijana tsa bohlokoa tse nang le-mocheso o phahameng oa tšepe, ho lokisoa ha lintho, le liphuputsong tsa laboratori. Litšobotsi tsa bona tsa tekheniki ka kotloloho li ama ts'ebetso ea ts'ebetso le boleng ba sehlahisoa. Tsoelo-pele ea theknoloji ea sejoale-joale ea crucible e mabapi le mahlale a thepa, thermodynamics, le moralo oa sebopeho, e leng se hlahisang melemo e fapaneng ea ts'ebetso.

Ho ea ka pono ea lintho tse bonahalang, li-crucibles li ka aroloa ka graphite, ceramics (joaloka alumina le zirconia), tšepe le lisebelisoa tse kopantsoeng. Li-crucible tsa graphite li sebelisoa haholo-ho qhibilihisa tšepe e seng ferrous ka lebaka la mocheso o phahameng oa mocheso,{2}}e hanyetsanang le mocheso o phahameng (ho fihla ho 3000 degrees ), le ho hanyetsa mocheso oa mocheso. Ka lehlakoreng le leng, li-crucible tsa ceramic li tsejoa ka ho se sebetse ha lik'hemik'hale 'me li loketse ho sebetsana le ho qhibiliha ha acidic le alkaline. Ka mohlala, li-crucibles tsa alumina li ka thibela ka katleho ho silafala ha litšila ka khōlo e le 'ngoe ea kristale ea silicon. Metal crucibles (joaloka tšepe{7}} le nickel{{8}based) hangata e sebelisoa litekong tse phahameng- tsa ho qhibilihisa khatello ka lebaka la matla a tsona a holimo. Lilemong tsa morao tjena, ho hlahisoa ha lisebelisoa tse kopantsoeng tse kang silicon carbide ho ntlafalitse le ho feta ho se mamelle le ho hanyetsa ha li-crucibles.

Mabapi le moralo oa sebopeho, sebopeho sa crucible le botenya ba lebota li tlameha ho ntlafatsoa ho latela litlhoko tsa ts'ebetso. Mohlala, li-crucibles tse sebelisoang ka har'a libopi tsa crystallization hangata li na le moralo o tlase ho khothaletsa pholiso e ts'oanang ea ho qhibiliha. Li-crucibles tse nyenyane tsa laboratori li hatisa marako a tšesaane bakeng sa karabo e potlakileng ea mocheso. Litheknoloji tsa kalafo ea holim'a metsi, joalo ka ho roala kapa ho kenya, le tsona li sebelisoa haholo. Ka ho etsa lera le sireletsang (mohlala, boron nitride coating) leboteng le ka hare la crucible, ba ka lelefatsa bophelo ba ts'ebeletso ea eona le ho fokotsa ho kenella ha tšepe e qhibilihisitsoeng.

Ho feta moo, tsoelo-pele ea theknoloji ea crucible e bonahala e sebelisana- le lisebelisoa tsa mocheso o phahameng. Mohlala, li-crucibles tse sebelisoang ka har'a libopi tsa vacuum induction li tlameha ho ts'oaroa hantle le kabo ea tšimo ea motlakase ho qoba mocheso o feteletseng oa lehae. Li-crucible tse sebelisoang lits'ebetsong tse tsoelang pele tsa ho lahla li hloka moralo o nepahetseng oa boema-kepe ho netefatsa phallo e tsitsitseng ea ho qhibiliha. Nakong e tlang, ka nts'etsopele ea lisebelisoa tse ncha le theknoloji e bohlale ea ho etsa, li-crucible li tla bonts'a ts'ebetso e ntlafetseng le ho feta libakeng tse feteletseng (tse kang lithempereichara tse phahameng{{4}le kutu e matla), e tla lebisa katlehong-ea makhaola-khang.
