I-Sapphire Crystal Growth Furnace KY Indlela ye-Kyropoulos ye-Sapphire Wafer kanye ne-Optical Window Production Isithombe Esifakiwe

Incazelo emfushane:

Lesi sixhobo sokukhulisa ikristalu yesafire sisebenzisa indlela ye-Kyropoulos (KY) ehamba phambili emhlabeni wonke, eklanyelwe ngokukhethekile ukukhula kwesafire eyodwa enobubanzi obukhulu, enesici esiphansi. Indlela ye-KY inika amandla ukulawula okunembile kokudonsa kwekristalu yembewu, isivinini sokuzungezisa, kanye nezinga lokushisa eliphansi, okuvumela ukukhula kwamakristalu esafire afinyelele kumayintshi angu-12 (300 mm) ububanzi emazingeni okushisa aphezulu (2000–2200°C). Amasistimu we-KY-method we-XKH asetshenziswa kakhulu ekukhiqizeni kwezimboni ama-2–12-inch C/A-plane amawafa esafire namafasitela abonakalayo, azuza ukukhishwa kwanyanga zonke kwamayunithi angu-20. Isisetshenziswa sisekela izinqubo ze-doping (isb, i-Cr³⁰ doping ye-ruby synthesis) futhi iletha ikhwalithi yekristalu nge:

Ukuminyana kokuhlukaniswa <100/cm²

Ukudlulisa >85% @ 400–5500 nm

Isimiso Sokusebenza

Umgomo oyinhloko wendlela ye-KY uhlanganisa ukuncibilika okuhlanzekile okuphezulu kwe-Al₂O₃ ku-tungsten/molybdenum crucible ku-2050°C. Ikristalu yembewu yehliselwa ekuncibilikeni, kulandelwa ukuhoxiswa okulawulwayo (0.5-10 mm/h) nokujikeleza (0.5-20 rpm) ukuze kuzuzwe ukukhula okuqondile kwamakristalu angama-α-Al₂O₃ owodwa. Izici ezibalulekile zifaka:
