Li-crucibles ke likarolo tsa bohlokoa tsa lisebelisoa tsa lik'hemik'hale 'me li sebetsa e le lijana tsa ho qhibilihisa le ho hloekisa maro a tšepe, hammoho le ho futhumatsa le ho sebetsana le metsoako ea metsi a tiileng.Li theha motheo oa ho netefatsa hore ho na le liphetoho tse bonolo tsa lik'hemik'hale.
Li-crucible li ka aroloa ka lihlopha tse tharo tse kholo:likotlolo tsa graphite, likotlolo tsa letsopa, le lithupa tsa tšepe.
Li-crucible tsa graphite li entsoe haholo ka graphite ea tlhaho ea kristale, e bolokang mefuta e fapaneng ea 'mele le ea lik'hemik'hale ea graphite ea tlhaho.Li na le conductivity e ntle ea mocheso le ho hanyetsa mocheso o phahameng.Nakong ea ts'ebeliso e phahameng ea mocheso, li bonts'a li-coefficients tse tlase tsa katoloso ea mocheso, li etsa hore li se ke tsa futhumala ka potlako le ho pholile.Li-crucible tsa graphite li na le khanyetso e matla ea kutu ho litharollo tsa asiti le alkaline mme li bonts'a botsitso bo botle ba lik'hemik'hale.
Ka lebaka la litšobotsi tsena tse phahameng, li-crucible tsa graphite li sebelisoa haholo liindastering tse kang metallurgy, casting, mechine le boenjiniere ba lik'hemik'hale.Ba fumana ts'ebetso e pharaletseng ha ho qhibilihisoa litšepe tsa lisebelisoa tsa alloy le ho qhibiliha ha litšepe tse se nang ferrous le metsoako ea tsona, e fanang ka melemo e hlokomelehang ea thekenoloji le moruo.
Lisebelisoa tsa Silicon Carbide:
Li-crucible tsa silicon carbide ke lijana tsa ceramic tse bōpehileng joaloka sekotlolo.Ha lintho tse tiileng li hloka ho futhumatsoa ka mocheso o phahameng, li-crucibles lia hlokahala hobane li khona ho mamella mocheso o phahameng ha o bapisoa le lisebelisoa tsa khalase.Li-crucibles hangata ha li tlatsoe ka bongata nakong ea ts'ebeliso ho thibela thepa e futhumetseng hore e se tšollele, e lumella moea hore o kene ka bolokolohi le ho thusa ho etsa hore oxidation e be teng.Ka lebaka la setsi sa bona se senyenyane, li-crucibles hangata li behoa holim'a kgutlotharo ea letsopa bakeng sa ho futhumatsa ka ho toba.Li ka behoa li otlolohile kapa li eme ka lehlakoreng la tšepe e meraro, ho itšetlehile ka litlhoko tsa liteko.Ka mor'a ho futhumatsa, li-crucibles ha lia lokela ho behoa hang-hang holim'a tšepe e batang ho qoba ho pholile ka potlako le ho senyeha ho ka bang teng.Ka ho tšoanang, ha lia lokela ho behoa ka ho toba holim'a holim'a lepolanka ho thibela kotsi ea ho chesa kapa ea mollo.Mokhoa o nepahetseng ke ho lumella litšepe hore li phole ka tlhaho holim'a thapo ea tšepe kapa ho li beha holim'a letlooa la asbestos bakeng sa ho pholile butle.Matlapa a crucible a lokela ho sebelisoa bakeng sa ho tšoara.
Lithako tsa Platinum:
Li-crucibles tsa platinum, tse entsoeng ka platinamo ea tšepe, li sebetsa e le likarolo tse ling tsa li-analyzer tse fapaneng tsa mocheso 'me li sebelisetsoa ho futhumatsa lisebelisoa tse se nang tšepe, tse kang tlhahiso ea fiber ea khalase le ho taka khalase.
Ha baa lokela ho kopana le:
Metsoako e tiileng e kang K2O, Na2O, KNO3, NaNO3, KCN, NaCN, Na2O2, Ba(OH)2, LiOH, joalo-joalo.
Aqua regia, tharollo ea halogen, kapa tharollo e khonang ho hlahisa li-halogen.
Metsoako ea litšepe tse fokolang habonolo le litšepe ka botsona.
Li-silicate tse nang le carbon, phosphorus, arsenic, sebabole le metsoako ea tsona.
Li-Crucible tsa Nickel:
Sebaka se qhibilihisang sa nickel ke likhato tse 1455 tsa Celsius, 'me mocheso oa sampuli ka har'a nickel crucible ha oa lokela ho feta likhato tse 700 tsa Celsius ho thibela oxidation ka mocheso o phahameng.
Li-crucibles tsa nickel li hanyetsana haholo le lintho tsa alkaline le kutu, li etsa hore li tšoanelehe bakeng sa li-alloys tsa tšepe tse qhibilihisang, slag, letsopa, lisebelisoa tsa refractory le tse ling.Li-crucible tsa nickel li lumellana le li-alkaline fluxes tse kang NaOH, Na2O2, NaCO3, le tse nang le KNO3, empa ha lia lokela ho sebelisoa le KHSO4, NaHSO4, K2S2O7, kapa Na2S2O7 le sulfide fluxes e nang le sebabole.Ho qhibiliha ha matsoai a aluminium, zinki, loto, tin le mercury ho ka etsa hore crucibles ea nickel e be bobebe.Li-crucible tsa nickel ha lia lokela ho sebelisoa bakeng sa ho chesa li-precipitates, 'me borax ha ea lokela ho qhibiliha ho tsona.
Hangata li-crucibles tsa nickel li na le likarolo tse ngata tsa chromium, kahoo ho lokela ho hlokomeloa ha nako e sitisoa.
