Melemo ea Botekgeniki ea Bohlokoa
Li-crucible tsa RBSC li sebetsa hantle ho feta li-counterparts tsa alumina le graphite tse tloaelehileng ka:
- Phetisetso e ikhethang ea mocheso (120–150 W/m·K ho 1000°C)
- Koefficient ea katoloso ea mocheso e tlase haholo (4.5×10⁻⁶/K)
- Ho hanyetsa ho thothomela ha mocheso ho mamella lipotoloho tse 50+ tse potlakileng tsa ho pholisa (1600°C →25°C)
- Ho hanyetsa ho ts'oha ha asiti/alkali (ho lumellana ha pH 0–14)
- Ho tsitsa ha oxidation moeeng ho fihlela ho 1650°C
Bokgoni ba Metallurgical
Tlhahisong ea tšepe ea alloy le ho qhibilihisa tšepe e seng ea ferrous (aluminium, koporo, zinki), li-crucible tsa RBSC li nolofalletsa:
- Sekhahla sa ho qhibiliha se potlakileng ka 20–30% ka phetiso e ntlafalitsoeng ea mocheso
- Tlhokomelo ea bohloeki ba tšepe ea 99.95% ka libaka tse sa sebetseng hantle
- Ho fokotseha ha sebopeho sa slag ka lebaka la ho fokotseha ha maemo a mocheso
- Bophelo bo bolelele ba tšebeletso (3–5× e telele ho feta di-crucible tsa letsopa-graphite)
Lisebelisoa tsa ho Lahla ka ho Sebetsa le tsa Mekaniki ka ho Sebetsa ...
Thepa e ikhethang ea mechini ea li-crucible e tšehetsa litlhoko tse thata tsa indasteri:
- Botšepehi bo tsitsitseng ba sebopeho tlas'a khatello ea mechine ea 15-20 MPa
- Botsitso bo tsitsitseng ba litekanyo (phetoho ea bophahamo ba modumo ea ± 0.1% ho 1500°C)
- Ts'ebetso e se nang tšilafalo bakeng sa likarolo tsa sehlopha sa lifofane
- Tshebetso e tšepahalang lits'ebetsong tsa ho lahla tsa centrifugal
Bokhabane ba Ts'ebetso ea Lik'hemik'hale
Li-crucible tsa RBSC li sebetsana le liphephetso tse kholo tlhahisong ea lik'hemik'hale:
- Ho boloka letsoai le qhibilihisitsoeng ka mokhoa o sireletsehileng (mohlala, NaOH, KNO₃)
- Ts'ebetso e tsitsitseng liketsong tsa sulfidation/chlorination
- Khanyetso ea ts'enyeho khahlanong le HF ho fihlela ho 800°C
- Polokeho ea bohloeki ho ntšoeng ha lintho tse sa tloaelehang tsa lefats'e
Moruo oa Ts'ebetso
Leha litšenyehelo tsa pele li le holimo ka 40-60% ho feta li-crucible tsa setso, litharollo tsa RBSC li fana ka:
- Phokotso ea 70% ea makhetlo a ho nkela sebaka
- Poloko ea matla ea 25–35% ka ho ntlafatsa ts'ebetso ea mocheso
- 90% ea ho sebelisoa hape ha thepa ka ho sebelisa mocheso hape
- Litlhoko tsa tlhokomelo tse batlang li le lefela
Lintlafatso tse Ikhethang tsa Indasteri
1. Tlhahiso ea Titanium Alloy
- E mamella ho qhibiliha ha Ti e arabelang mochesong oa 1700°C
- E thibela tšilafalo ea khabone
2. Ho Kopanya Thepa ea Betri
- E nolofalletsa ts'ebetso ea cathode ea LiCoO₂ e tšoanang
- E hanela ho bola ha letsoai la lithium
3. Kgolo ya Kristale ya Semiconductor
- E boloka ho lumellana ha vacuum e phahameng haholo
- E felisa tšilafalo ea silicon carbide
Moralo oa Nakong e Tlang
Li-crucible tsa sejoale-joale tsa RBSC li kenyelletsa likarolo tse tsoetseng pele:
- Meaho ea marotholi a gradient bakeng sa ho kenella ha khase ho laoloang
- Liaparo tsa bokaholimo tse nang le boholo bo fokolang tse ntlafatsang khanyetso ea slag
- Li-sensor tsa mocheso tse kentsoeng bakeng sa ho beha leihlo ts'ebetso
