Tlhaloso e Khutšoanyane:

Tube ena ea safire e sebetsang hantle e entsoe ka mekhoa e 'meli ea Czochralski (CZ) le Kyropoulos (KY), ho netefatsa boleng bo phahameng le ho nepahala. E entsoe ka 99.999% e hloekileng ea Al₂O₃ sapphire e le 'ngoe ea kristale, tube ena e na le ho hlaka ho hoholo le matla a ikhethang a mochini. Ka ho hanyetsa mocheso o phahameng, e khona ho mamella maemo a feteletseng, e leng se etsang hore e be se loketseng bakeng sa likopo tse libakeng tse thata tse kang ho sebetsa ha semiconductor, libopi tsa mocheso o phahameng, le liindasteri tsa lik'hemik'hale.

Sapphire, ka ho thatafala ha eona ho sa tloaelehang, e maemong a ka tlase ho daemane, e fana ka khanyetso e phahameng ka ho fetesisa. Ho feta moo, botsitso ba eona bo ikhethang ba mocheso bo lumella ho sebetsa ka mokhoa o tsitsitseng ts'ebetsong ea mocheso o phahameng. Sebopeho sa kristale se le seng sa tube se tiisa ho se sebetse hantle ha lik'hemik'hale le ho tsamaisa mocheso, ho bohlokoa bakeng sa ts'ebeliso e nepahetseng.
Tube ena ea safire e loketse liindasteri tse ngata tse hlokang, ho kenyelletsa le sefofane, optics, elektronike le boenjiniere ba lik'hemik'hale, moo ho tšoarellang, ho hanyetsa mocheso le bohloeki li leng bohlokoa. Ts'ebetso ea eona e tsoetseng pele ea tlhahiso e tiisa sehlahisoa se ka tšeptjoang, se netefatsang tšebeliso ea nako e telele le botsitso tlas'a maemo a feteletseng a ts'ebetso.
