Mokhoa oa Sapphire Single Crystal Ingot ky Al2O3

Tlhaloso e Khutšoanyane:

Kristale ea safire ke kristale e le 'ngoe ea boleng bo holimo e holisitsoeng ho tsoa ho aluminium oxide e hloekileng haholo (Al₂O₃) ho sebelisoa mokhoa oa Kyropoulos (KY) kapa mekhoa e meng e tsoetseng pele ea ho hula. Ingot e hlahisoang e nang le cylindrical kapa tapered e na le bokaholimo bo boreleli, bo teteaneng le liphoso tse fokolang tsa ka hare. Ka thepa e ikhethang ea optical, mechanical, le lik'hemik'hale, safire e fetohile thepa ea bohlokoa bakeng sa optoelectronics, semiconductors, le elektroniki ea bareki ea boleng bo holimo.

- Tekanyo e tsitsitseng ea refractive e ka bang 1.76, e nolofalletsang ho nka litšoantšo le phetisetso e nepahetseng ea mahlo.
Litšobotsi tse Ikhethang tsa Thermal
- Sebaka se phahameng sa ho qhibiliha sa ~2050 °C se dumella tshebetso e tshepahalang dibakeng tse nang le mocheso o phahameng.
- Ho tsamaisa mocheso hantle (≈35 W/m·K mochesong oa kamore) ho tšehetsa ho qhala ha mocheso ka katleho.
Botsitso bo Phahameng ba Lik'hemik'hale
- E hanela li-acid, li-alkali, spray ea letsoai le boholo ba li-solvents tsa tlhaho.
- E dula e sa sebetse ka dikhemikhale ka har'a vacuum, dikhase tse sa sebetseng, le sepakapaka se matla se oxidating kapa se fokotsang oksijene.
Ho Ts'ebetso le ho Tšoana
- Likristale tse holisitsoeng ka KY li bontša bophara bo lekanang le khatello e tlase ea ka hare.
- E ka sehoa, ea bentšoa, 'me ea koaheloa ho latela litlhaloso tsa bareki, ka ho ba le makukuno a bokaholimo a ka tlase ho Ra ≤ 0.2 nm.
