Sapphire Ib Leeg Crystal Ingot ky txoj kev Al2O3

Kev Piav Qhia Luv:

Sapphire siv lead ua yog ib qho siv lead ua zoo uas loj hlob los ntawm cov txhuas oxide siab (Al₂O₃) siv txoj kev Kyropoulos (KY) lossis lwm yam kev rub siab heev. Cov ingot cylindrical lossis tapered uas tshwm sim muaj qhov chaw du, ntom thiab tsawg kawg nkaus sab hauv qhov tsis zoo. Nrog rau cov khoom siv kho qhov muag, kho tshuab, thiab tshuaj lom neeg zoo heev, sapphire tau dhau los ua cov khoom siv tseem ceeb rau optoelectronics, semiconductors, thiab cov khoom siv hluav taws xob zoo rau cov neeg siv khoom.
