Sebakeng sa metallurgy, k'hemistri, le saense ea lintho tse bonahalang, khetho ea se nepahetsengcruciblethepa e bohlokoa ho fumana katleho ea lits'ebetso tse fapaneng, ho tloha ho alloying ea tšepe e nang le mocheso o phahameng ho isa ho kopantseng lirafshoa le likhalase tse tsoetseng pele. Ho na le lisebelisoa tse 'maloa tsa crucible tse fumanehang, e' ngoe le e 'ngoe e na le thepa ea eona e ikhethang le melemo. Ha re hlahlobeng lisebelisoa tse ntle ka ho fetisisa tsa li-crucibles ka botlalo:
Li-Crucible tsa Quartz
Li-crucible tsa quartz, tse atisang ho etsoa ka silika e entsoeng ka bohloeki bo phahameng, li tsebahala ka litšoaneleho tsa tsona tse ikhethang. Ba ipabola ka ho hanyetsa mocheso o phahameng, ho mamella liphello tse senyang tsa li-acids le metheo, le ho boloka botsitso tlas'a maemo a feteletseng a mocheso. Li-crucibles tsena li fumana sebaka sa tsona sa ho qhibilihisa litšepe tse hloekileng tse kang silicon, aluminium le tšepe. Ho feta moo, conductivity ea bona e phahameng ea mocheso e ntlafatsa ts'ebetso ea ho qhibiliha. Leha ho le joalo, boleng ba premium ba quartz bo tla ka theko e phahameng.
Lithako tsa Ceramic
Li-crucible tsa ceramic li kenyelletsa likarolo tse peli tse kholo: aluminium oxide ceramics le zirconium oxide ceramics. Li-crucibles tsena li fana ka khanyetso e ntle ea mocheso le botsitso ba lik'hemik'hale, li li etsa khetho e fapaneng ea ho qhibilihisa mefuta e mengata ea lisebelisoa, ho kenyeletsoa litšepe, likhalase, lirafshoa le tse ling. Leha ho le joalo, khanyetso ea bona ea mocheso e batla e le tlase ho feta ea li-crucible tsa quartz, e leng se etsang hore li tšoanelehe bakeng sa lisebelisoa tse nang le lintlha tse qhibilihisang ka tlase ho 1700 ° C.
Graphite Crucibles
Li-graphite crucibles ke lipere tsa maemo a phahameng a mocheso, maemo a khatello e phahameng, hangata a sebetsa e le lisebelisoa tsa bohlokoa lipatlisisong tsa metallurgical le lik'hemik'hale. Li-crucibles tsena li fumaneha ka mefuta e 'meli ea mantlha: graphite ea tlhaho le graphite ea maiketsetso. Li-crucible tsa tlhaho tsa graphite li ithorisa ka botsitso bo phahameng ba mocheso le ho hanyetsa kutu, tse loketseng lisebelisoa tse fapaneng tsa mocheso o phahameng. Ka lehlakoreng le leng, li-crucible tsa maiketsetso tsa graphite li na le chelete e ngata empa li ka 'na tsa fokotsa botsitso le ho hanyetsa ha kutu.
Metal Crucibles
Li-crucible tsa tšepe li hahiloe ka thepa e kang tšepe e sa hloekang, molybdenum, platinamo le tse ling. Ke khetho eo u ka e khethang ha u sebetsana le lisebelisoa tse nang le libaka tse qhibilihang haholo kapa ha u tobane le maemo a asiti haholo kapa a alkaline. Metal crucibles e bontša khanyetso e matla ho kutu le ho boloka botsitso bo tsotehang ba mocheso. Leha ho le joalo, tšebeliso ea bona e amahanngoa le litšenyehelo tse phahameng ha li bapisoa le lisebelisoa tse ling tsa crucible.
Summary
Tkhetho ea thepa ea crucible e lokela ho tsamaisoa ke lisebelisoa tse khethehileng tse ntseng li sebetsoa le maemo a teng a ho qhibiliha. Mofuta o mong le o mong oa crucible o fana ka melemo le mefokolo ea oona e ikhethang, 'me ho khetha e nepahetseng ke habohlokoa bakeng sa ho finyella liphello tse sebetsang hantle le tsa boleng bo phahameng masimong a metallurgy, chemistry le science science.
