Talosaga:
Lanthanum Fluoride, e masani ona faʻaaogaina i tioata faʻapitoa, vai togafitiga ma faʻamalosi, faʻapea foʻi ma mea autu autu mo le faia o Lanthanum Metal. Lanthanum Fluoride (LaF3) o se vaega taua o se tioata mamafa Fluoride igoa ZBLAN. O lenei tioata e sili atu le felauaiga i le infrared range ma o lea e faʻaaogaina mo faiga fesoʻotaʻiga fiber-optical. Lanthanum Fluoride o lo'o fa'aaogaina i fa'aofuofu moli phosphor. Faʻafefiloi ma Europium Fluoride, e faʻaaogaina foi i le tioata tioata o le Fluoride ion-selective electrodes.Lanthanum fluoride o lo'o fa'aaogaina e saunia ai scintillators ma mea e le masani ai le lalolagi tioata leisa e mana'omia e tekinolosi fa'aaliga fa'afoma'i fa'aonaponei ma le saienisi faaniukilia. Lanthanum fluoride o lo'o fa'aaogaina e fai ai le tioata fa'afefeteina alava mata ma se tioata infrared eleele. Lanthanum fluoride o lo'o fa'aaogaina i le gaosiga o moli arc carbon electrodes i puna moli. Lanthanum fluoride o lo'o fa'aaogaina i su'esu'ega vaila'au e gaosia ai eletise filifilia o le fluoride ion.

Metotia fa'akomepiuta
1. Fa'amuta le lanthanum oxide ile hydrochloric acid ile vaila'au ma fa'afefe ile 100-150g/L (fa'atatau ile La2O3). Fa'avevela le vaifofo i le 70-80 ℃, ona fa'afefe ai lea ile 48% hydrofluoric acid. E fufulu, fa'amama, fa'agogo, nutililii, ma fa'amama fa'amama e maua ai le lanthanum fluoride.
2. Tu'u le vaifofo LaCl3 o lo'o iai le vaila'au oona i totonu o se ipu platinum ma fa'aopoopo i ai le 40% hydrofluoric acid. Liligi i fafo le tele o le vai ma fa'agogo le toega o totoe.
