Codsiga:
Lanthanum Fluoride, waxaa inta badan lagu dabaqaa galaas khaas ah, daaweynta biyaha iyo kicinta, iyo sidoo kale sida alaabta ceeriin ee ugu weyn ee samaynta Lanthanum Metal. Lanthanum fluoride (LaF3) waa qayb muhiim ah oo ka mid ah galaaska Fluoride ee culus oo lagu magacaabo ZBLAN. Muraayadani waxay leedahay gudbin heer sare ah oo ku jirta kala duwanaanta infrared-ka, sidaas darteed waxaa loo isticmaalaa hababka isgaarsiinta fiber-optical. Lanthanum Fluoride waxaa loo isticmaalaa daaha laambad fosfoor ah. Lagu qaso Europium Fluoride, waxa kale oo lagu dabaqaa xuubka crystal-ka ee Fluoride ion-selective electrodes.Lanthanum fluoride waxa loo isticmaalaa in lagu diyaariyo scintilators iyo qalabka laser crystal dhul dhif ah looga baahan yahay technology bandhigay muuqaalka caafimaadka casriga ah iyo sayniska nuclear. Lanthanum fluoride waxa loo isticmaalaa in lagu sameeyo galaas fluoride fiber optic fiber iyo galaas dhul dhif ah infrared. Lanthanum fluoride waxaa loo isticmaalaa soo saarista laambada arc kaarboonka ee ilaha iftiinka. Lanthanum fluoride loo isticmaalo falanqaynta kiimikada si loo soo saaro fluoride ion electrodes.

Habka synthetic
1. Ku milmi lanthanum oxide ee hydrochloric acid hab kiimiko oo ku milo 100-150g/L (oo lagu xisaabiyo sida La2O3). Kuleyli xalka 70-80 ℃, ka dibna ku daadi 48% hydrofluoric acid. Roobka waa la dhaqaa, la sifeeyaa, la qalajiyaa, la jajabiyaa, oo faakuumku fuuqbaxay si loo helo fluoride lanthanum.
2. Ku rid xal LaCl3 oo ka kooban hydrochloric acid saxan platinum oo ku dar 40% hydrofluoric acid. Ku shub dareere xad-dhaaf ah oo uumi hadhaaga engegan.
