Isicelo:
I-Lanthanum Fluoride, isetshenziswa kakhulu endizeni ekhethekile, ukwelashwa kwamanzi kanye ne-catalyst, futhi njengezinto zokwakha eziphambili zokwenza i-lanthanum yensimbi. ILanthanum Fluoride (LAF3) iyingxenye ebalulekile yengilazi eyi-fluaride fluoride egama linguZblan. Le ngilazi inokudlulisela okuphezulu ebangeni le-infrared futhi ngakho-ke isetshenziselwa izinhlelo zokuxhumana ze-fiber-optical. ILanthanum Fluoride isetshenziswa embonweni wamaLamp wePhosphor. Ihlanganiswe ne-Europium Fluoride, isetshenziswe futhi kulwelwesi lwe-crystal lwama-electrodes we-fluoride ion.lanthanum Fluoride ukulungiselela ama-scintillators kanye nezinto zombuso ezingavamile zomhlaba ezidingwa yisayensi yesimanje yombukiso wezokwelapha kanye nesayensi yenuzi. ILanthanum Fluoride isetshenziselwa ukwenza i-fluoride ingilazi fiber optical fiber kanye nengilazi yomhlaba engavamile. I-Lanthanum Fluoride isetshenziswa ekwakhiweni kwe-ARC Lamp Carbon Electrotes emithonjeni yokukhanyisa. I-Lanthanum Fluoride esetshenziswe ekuhlaziyweni kwamakhemikhali ukukhiqiza ama-electrodes akhethiwe we-fluoride ion.

Indlela yokwenziwa
1. Disolsolsolve LANthanum oxide e-hydrochloric acid ngendlela yamakhemikhali futhi ugcwale ku-100-150g / l (kubalwa njengeLa2o3). Shisisa isixazululo ku-70-80 ℃, bese unqamula nge-48% hydrofluoric acid. Ukuhanjiswa kwezulu kuyagezwa, kuhlanjululwe, kumiswe, kuchotshozwa, futhi kwangenwa yi-vacuum emzimbeni ukuthola i-lanthanum fluoride.
2. Beka isixazululo se-lacl3 equkethe i-hydrochloric acid endishini yeplatinamu bese wengeza ama-40% hydrofluoric acid. Thela uketshezi ngokweqile bese uqubuka izinsalela zomile.
