Thermal Conductivity
- Li-crucible tsa graphitebonts'a conductivity e ntle ea mocheso, ho netefatsa hore ho fanoa ka mocheso o tšoanang. Thepa ena e fokotsa libaka tse chesang 'me e etsa bonnete ba hore e qhibiliha, e etsa hore e sebetse hantle bakeng sa litšepe tse kang khauta, koporo le aluminium.
- Thermal conductivity ka fihla ho boleng ba ho fihla ho 100 W/m·K, e leng e phahameng ha e bapisoa le thepa ea khale ea refractory.
Ho hanyetsana le Mocheso o Phahameng
- Li-crucible tsa graphitee khona ho mamella mocheso o phahameng haholo, ho fihlela ho 1700°Csepakapaka se se nang moya kapa maemo a vacuum. Sena se ba lumella ho boloka botšepehi ba sebopeho maemong a boima ntle le ho theola seriti.
- Li-crucibles tsena li lula li tsitsitse ebile li hanana le deformation tlas'a mocheso o matla.
Coefficient e tlase ea Katoloso ea Thermal
- Lisebelisoa tsa graphite li na le acoefficient e tlase ea katoloso ea mocheso(Ka tlase ho 4,9 x 10 ^ -6 / ° C), ho fokotsa kotsi ea ho akheha kapa ho makala ha molumo ha li pepesoa liphetoho tse potlakileng.
- Tšobotsi ena e etsa hore li-crucible tsa graphite li tšoanelehe ka ho khetheha bakeng sa lits'ebetso tse kenyelletsang nako ea ho futhumatsa le ho pholisa khafetsa.
Khanyetso ea Corrosion
- Graphite ha e sebetse ka lik'hemik'hale 'me e fanakhanyetso e phahameng ho li-acids tse ngata, alkalis le lintho tse ling tse senyang, haholo-holo ho fokotsa kapa ho se nke lehlakore. Sena se etsa hore li-crucible tsa graphite e be tse loketseng tikolohong ea lik'hemik'hale tse mabifi tsa ho lahla kapa ho hloekisa.
- Ho hanyetsa ha thepa ho oxidation ho ka ntlafatsoa le ho feta ka ho roala kapa ho phekoloa ka mokhoa o khethehileng, ho netefatsa bophelo ba nako e telele ea tšebeletso.
Motlakase Conductivity
- E le conductor e ntle ea motlakase, lisebelisoa tsa graphite li loketse lits'ebetso tsa ho futhumatsa ka induction. Motlakase o phahameng oa motlakase o nolofalletsa ho kopana ka katleho le mekhoa ea ho kenya letsoho, ho netefatsa hore mocheso o potlakileng le o tšoanang.
- Thepa ena e bohlokoa haholo lits'ebetsong tse hlokangli-crucibles tsa heater ea induction, ho matlafatsa ts'ebetso ea ts'ebetso liindastering tse kang mosebetsi oa ho theha kapa oa metallurgy.
Bohloeki le Sebopeho sa Lintho
- Li-crucible tsa carbon graphite tse hloekileng haholo(ho fihlela ho 99,9% bohloeki) ba bohlokoa bakeng sa likopo moo litšila tsa tšepe li tlameha ho qojoa, joalo ka tlhahiso ea tšepe tse bohlokoa kapa tsa ceramics tsa bohlokoa.
- Lithako tsa silicon carbide graphite cruciblesKopanya thepa ea graphite e ka bang lerako, e nang le moea o ntlafalitsoeng, ho hanyetsa oforametso ho phahameng le ntlha e qhibilihang, e loketseng maemo a feteletseng.
Ho tšoarella le ho phela halelele
- Lithako tsa graphite tse hatelitsoeng ka Isostaticallyli etsoa ho ba le letsoalo le matla, li etsa hore li-pfrans li iphetetsang le ho fokotsoa ka nama nakong ea ts'ebetso ea mocheso oa mocheso o phahameng. Li-crucibles tsena li boetse li hanyetsana le khoholeho ea mobu le tšenyo ea mechine.
Sebopeho sa Lik'hemik'hale:
- Khabone (C): 20-30%
- Silicon Carbide (SiC)50-60%
- Alumina (Al2O3)3-5%
- Ba bang3-5%
Boholo le libopeho tseo u ka li khethang
- Li-crucible tsa rona tsa graphite li fumaneha ka mefuta e mengata e fapaneng ea boholo le litlhophiso. Ho tlohalikotlolo tse nyane tsa graphite(E loketse tlhahlobo ea mabelo a lab
- Li-crucibles tse nang le graphitele crucibles withtšela li-spoutse ka boela ea etsoa ho latela litlhoko tse khethehileng tsa ho lahla, ho netefatsa boiketlo le bokhoni ba ho sebetsana le tšepe.
