Li-crucibleske lisebelisoa tsa bohlokoa liindastering tse fapaneng bakeng sa ho sebetsana le lits'ebetso tsa ho qhibiliha le ho qhibilihisa. Ke setshelo se kgonang ho mamella mocheso o phahameng mme se sebedisetswa ho tshwara dintho le ho di futhumatsa ho fihlela moo di qhibidihang teng. Mefuta e fapaneng ea li-crucibles e sebelisoa ho itšetlehile ka litlhoko tse khethehileng tsa thepa e qhibilihisitsoeng kapa e qhibilihisitsoeng. Ka poso ena ea blog, re tla hlahloba mefuta e fapaneng ea li-crucibles le ts'ebeliso ea tsona.
1. Sekoahelo sa tšepe:
Sebelisa crucible ea tšepe ha u qhibiliha lintho tse matla tsa alkaline tse kang NaOH. Leha ho le joalo, ha e so sebelisoe haholo ka lebaka la mathata a kang mafome a bonolo le oxidation. Lits'ebetsong tse ngata tse kenyelletsang lisebelisoa tsa alkaline, li-crucible tsa tšepe tse inert li lula e le khetho e ratoang.
2. Sekoahelo sa tšepe:
Li-crucible tsa tšepe tse entsoeng ka tšepe li entsoe ka tšepe ea kolobe 'me li tsebahala ka ho tšoarella ha tsona. E sebelisoa ho qhibilihisa li-alloys tse fapaneng tsa tšepe tse kenyelletsang aluminium, zinki, lead, tin le lialloys tsa antimony. Ha li bapisoa le li-crucibles tsa tšepe, li-crucibles tsa tšepe li tšoarella nako e telele 'me li ka mamella mocheso o phahameng o hlokahalang ho qhibilihisa li-alloys tsena.
3. Quartz crucible:
Li-quartz crucibles li sebelisoa hangata indastering ea semiconductor mme li bohlokoa bakeng sa tlhahiso ea lipotoloho tse kholo tse kopaneng. Li-crucibles tsena li khona ho mamella mocheso ho fihlela ho likhato tse 1650 'me li fumaneha ka mefuta e hlakileng le e hlakileng. Translucent quartz crucible e entsoeng ka mokhoa oa arc, e sebelisetsoang ho hula silicon e le 'ngoe ea kristale e bophara bo boholo. E na le melemo ea bohloeki bo phahameng, ho hanyetsa mocheso o matla, boholo bo boholo, ho nepahala ho phahameng, ts'ebetso e ntle ea ho kenya mocheso oa mocheso, ho boloka matla le boleng bo tsitsitseng. Leha ho le joalo, tlhokomelo e lokela ho nkoa kaha quartz e brittle 'me e ka robeha habonolo.
4. Porcelain crucible:
Li-crucible tsa ceramic li ratoa ka lebaka la ho hanyetsa lik'hemik'hale le ho khoneha. Leha ho le joalo, e ke ke ea sebelisoa ho qhibilihisa lintho tsa alkaline tse kang NaOH, Na2O2, Na2CO3, joalo-joalo, hobane li tla itšoara ka porcelain le ho baka kutu. Ho phaella moo, li-crucibles tsa porcelain ha lia lokela ho kopana le hydrofluoric acid. Li loketse ho sebelisoa ka mocheso o pota-potileng likhato tse 1200.
5. Corundum crucible:
Corundum crucible e loketse haholo bakeng sa ho qhibiliha disampole ho sebelisa lintho tse fokolang tsa alkaline tse kang anhydrous Na 2 CO 3 e le phallo. Leha ho le joalo, ha li tšoanelehe bakeng sa ho qhibiliha lisampole tse sebelisang lintho tse matla tsa alkaline (tse kang Na2O2, NaOH) kapa lintho tse nang le asiti (joalo ka K2S2O7) joalo ka fluxes.
6. Sekoahelo sa Graphite:
Li-crucible tsa graphite li sebelisoa haholo indastering ea ho lahla tšepe ka lebaka la conductivity ea tsona e ntle ea mocheso le ho hanyetsa mocheso o phahameng. Li loketse ho qhibilihisa mefuta e sa tšoaneng ea litšepe tse akarelletsang koporo, khauta, silevera le koporo.
7. Silicon carbide crucible:
Li-silicone carbide crucibles li tsebahala ka conductivity ea tsona e phahameng ea mocheso le khanyetso e ntle ea lik'hemik'hale. Li sebelisoa mekhoeng ea ho qhibilihisa le ho qhibilihisa e kenyelletsang mocheso o phahameng oa mocheso, joalo ka tlhahiso ea lirafshoa le li-alloys.
Mofuta o mong le o mong oa crucible o na le melemo le lits'ebetso tse ikhethang. Khetho ea crucible e itšetlehile ka lintlha tse kang ho qhibiliha kapa ho qhibiliha, mocheso o lakatsehang le tekanyetso. Ho sa tsotellehe hore na u qhibilihisa koporo, tšepe ea tšepe kapa li-alloys tse qhibilihisang, ho khetha crucible e nepahetseng ke habohlokoa bakeng sa ts'ebetso e atlehileng le e sebetsang.
Ka kakaretso, li-crucibles li bapala karolo ea bohlokoa liindastering tse fapaneng tse amanang le ts'ebetso ea ho qhibiliha le ho qhibiliha. Ho utloisisa mefuta e fapaneng ea li-crucible tse fumanehang le lits'ebetso tsa tsona tse ikhethileng ho ka thusa likhoebo ho etsa liqeto tse nang le tsebo mabapi le hore na li ka sebelisa crucible efe ho fihlela litlhoko tsa bona tse ikhethileng. Ebang ke tšepe ea tšepe, crucible ea tšepe, quartz crucible, porcelain crucible, corundum crucible, graphite crucible kapa silicon carbide crucible, mofuta o mong le o mong o na le melemo le mefokolo ea oona. Ka ho khetha crucible e nepahetseng, likhoebo li ka ntlafatsa ts'ebetso ea tsona le ho netefatsa liphetho tsa boleng bo holimo.
