Isicelo:
I-Lanthanum Fluoride, isetshenziswa ikakhulukazi engilazini ekhethekile, ukwelashwa kwamanzi kanye ne-catalyst, futhi njengezinto zokusetshenziswa eziyinhloko zokwenza i-Lanthanum Metal. I-Lanthanum Fluoride (LaF3) iyingxenye ebalulekile yengilazi yeFluoride esindayo ebizwa ngokuthi i-ZBLAN. Le glass ine-transmittance ephakeme kakhulu ebangeni le-infrared ngakho-ke isetshenziselwa izinhlelo zokuxhumana ze-fiber-optical. I-Lanthanum Fluoride isetshenziswa ekugqokeni kwesibani se-phosphor. Ixutshwe ne-Europium Fluoride, iphinde isetshenziswe kulwelwesi lwekristalu lwe-Fluoride ion-selective electrode.I-Lanthanum fluoride isetshenziselwa ukulungisa ama-scintillator nezinto ezingavamile ze-crystal crystal emhlabeni ezidingwa ubuchwepheshe besimanje bokuboniswa kwezithombe zezokwelapha nesayensi yenuzi. I-Lanthanum fluoride isetshenziselwa ukwenza i-fluoride glass optical fiber kanye nengilazi ye-infrared yomhlaba engavamile. I-Lanthanum fluoride isetshenziswa ekukhiqizeni i-arc lamp carbon electrode emithonjeni yokukhanyisa. I-Lanthanum fluoride esetshenziswa ekuhlaziyeni amakhemikhali ukwenza ama-electrode e-fluoride ion akhethiwe.

Indlela yokwenziwa
1. Chaza i-lanthanum oxide ku-hydrochloric acid ngendlela yamakhemikhali futhi unciphise ibe ngu-100-150g/L (kubalwa njenge-La2O3). Shisisa ikhambi libe ngu-70-80 ℃, bese ushisa ngo-48% we-hydrofluoric acid. Imvula iyagezwa, ihlungwe, yomiswe, igaywe, futhi ikhishwe ngamanzi ukuze kutholwe i-lanthanum fluoride.
2. Faka isixazululo se-LaCl3 esine-hydrochloric acid esitsheni seplatinamu bese wengeza u-40% we-hydrofluoric acid. Thela uketshezi oluningi bese uhwamulisa insalela yomile.
