Sapphire Ib Leeg Crystal Ingot
Daim duab qhia ntxaws
Txheej txheem cej luam
Sapphire siv lead ua yog ib qho zoo siv lead ua uas loj hlob los ntawm high-purity aluminium oxide (Al₂O₃) siv txoj kev Kyropoulos (KY) los yog lwm yam kev rub tawm siab heev. Lub resulting cylindrical los yog tapered ingot nta ib tug du, ntom ntom thiab me me qhov tsis xws luag. Nrog rau qhov zoo tshaj plaws kho qhov muag, txhua yam, thiab tshuaj muaj zog, sapphire tau dhau los ua cov khoom tseem ceeb rau optoelectronics, semiconductors, thiab cov khoom siv hluav taws xob zoo tshaj.
