Bohloeki bo phahameng ba tungsten crucible bakeng sa kholo ea kristale le vacuum coating
Tungsten crucible ea rona ke sets'oants'o sa maemo a holimo se etselitsoeng maemo a mocheso o phahameng haholo le a senyang. E entsoe ka tungsten ea boleng bo holimo kapa tungsten alloy, crucible ena e fana ka nako e telele, botsitso ba mocheso le ho hanyetsa ho bola ha lik'hemik'hale. E sebelisoa haholo liindastering tse kang khōlo ea kristale, coating ea vacuum, tlhahiso ea semiconductor, le metallurgy.

Khōlo ea Crystal
- Tlhaloso: Li-crucible tsa Tungsten li sebelisoa khōlong ea likristale tse le 'ngoe, tse kang safire, silicon le silicon carbide.
- Melemo: Sebaka se phahameng sa ho qhibiliha le botsitso ba mocheso li netefatsa kholo ea kristale e tšoanang.
- Lisebelisoa: Ho etsoa ha LED, lisebelisoa tsa optical, le li-wafers tsa semiconductor.
Vacuum Coating
- Tlhaloso: Li-crucible tsa Tungsten li loketse bakeng sa lits'ebetso tsa Physical Vapor Deposition (PVD) le Chemical Vapor Deposition (CVD).
- Melemo: Excellent mogote conductivity le ho hanyetsa mocheso phahameng.
- Lisebelisoa: Liaparo tsa filimi tse tšesaane bakeng sa lisebelisoa tsa elektroniki, liphanele tsa letsatsi le lisebelisoa tsa mahlo.
Bokaholimo ba tungsten crucible bo tla oxidize ka lebaka la ho pepesehela oksijene mochesong o phahameng. Tungsten ke tšepe e refractory e nang le ntlha e phahameng ea ho qhibiliha, empa ha e sireletsehe ka ho feletseng ho oxidation. Lintlha tse latelang ke tse ling tsa bohlokoa tse bakang tungsten oxidation:
1. Mocheso o Phahameng: Ha mocheso o le holimo, tungsten e arabela ka oksijene moeeng. Sekhahla sa oxidation se eketseha haholo ka mocheso o ntseng o eketseha, haholo-holo ka holimo ho 400°C (752°F).
2. Ho ba teng ha Oksijene: Ho ba teng ha oksijene ke ntlha ea bohlokoa. Oxidation e ka etsahala haholo ha tungsten e pepesehile moeeng kapa sepakapaka se nang le oksijene.
3. Ho thehoa ha tungsten oxide: Ha tungsten e na le oxidized, e etsa li-oxide tsa tungsten, tse kang tungsten trioxide (WO3) le tungsten dioxide (WO2). Li-oxide tsena li etsa lera holim'a tungsten crucible, e amang thepa ea eona le ts'ebetso ea eona.
4. Lintho tse silafatsang: Ho ba teng ha lintho tse ling tse silafatsang kapa likhase tse sebetsang li ka boela tsa khothalletsa ho ba le oxidation. Ka mohlala, halogens kapa mongobo o ka mpefatsa ts'ebetso ea oxidation.
5. Tšireletso ea Tšireletso: Lits'ebetsong tse ling, li-crucible tsa tungsten li ka 'na tsa koaheloa ka lisebelisoa tse sireletsang ho fokotsa oxidation. Leha ho le joalo, haeba liphahlo tsena li senyehile kapa li sa lekana, ho tla etsahala oxidation.
Ho fokotsa oxidation, li-crucibles tsa tungsten li atisa ho sebelisoa tlas'a khase ea inert (e kang argon kapa nitrogen) kapa maemo a vacuum, a thusang ho thibela ho itšoara ka oksijene. Ho ts'oaroa le ho boloka hantle ho bohlokoa hape ho fokotsa ho pepesehela tikoloho ea oxidizing.
Bophelo ba ts'ebeletso ea tungsten crucible bo ka fapana haholo ho latela lintlha tse 'maloa, ho kenyelletsa:
1. Mocheso oa ho sebetsa: Li-crucible tsa Tungsten hangata li sebelisoa ka mocheso o phahameng, 'me bophelo ba bona ba tšebeletso bo tla angoa ke mocheso oa bona o khethehileng oa ho sebetsa. Ha mocheso o phahame, lebelo la oxidation le ho senyeha hoa potlako.
2. Atmosphere: Tikoloho eo crucible e sebelisoang ho eona e phetha karolo ea bohlokoa. Sebakeng se sa sebetseng (joalo ka argon kapa naetrojene), bophelo ba ts'ebeletso ea tungsten crucible bo bolelele haholo ho feta crucible e pepesehileng moeeng kapa likhase tse sebetsang, hobane moea kapa likhase tse sebetsang li tla potlakisa oxidation.
3. Boleng ba Lintho: Ho hloeka le boleng ba tungsten e sebelisoang ka crucible ea hau le eona e tla ama nako ea eona ea bophelo. Tungsten e phahameng ea bohloeki ha e na monyetla oa ho ba le litšila tse bakang ho hloleha pele ho nako.
4. Maemo a Tšebeliso: Tšebeliso e khethehileng, ho kenyelletsa le mofuta oa thepa e qhibilihang kapa e sebetsoang, e tla ama bophelo ba crucible. Lisebelisoa tse ling li ka 'na tsa itšoara ka tungsten kapa tsa hlahisa litšila tse ka senyang crucible.
5. Thermal Cycling: Ho futhumatsa le ho pholile ka makhetlo a mangata ho ka baka khatello ea mocheso le mokhathala, tse ka khutsufatsang bophelo ba crucible.
6. Tlhokomelo le Tlhokomelo: Ts'ebetso e nepahetseng, ho hloekisa le ho hlokomela ho ka eketsa bophelo ba tungsten crucible ea hau. Ho qoba tšenyo ea mechine le ho etsa bonnete ba hore ha e tlas'a ho apara ho sa hlokahaleng ho tla thusa.
Ka kakaretso, tlas'a maemo a nepahetseng (khase ea inert, mocheso o nepahetseng le ho sebetsana ka hloko), bophelo ba tšebeletso ea tungsten crucible bo tloha likhoeling tse 'maloa ho ea ho lilemo tse' maloa. Leha ho le joalo, tlas'a maemo a sa rateheng, bophelo ba eona ba tšebeletso bo ka khutsufatsoa haholo. Ho kgothaletswa ho hlahloba kamehla le ho hlahloba boemo ba crucible ho fumana hore na e lokela ho nkeloa sebaka neng.
