Lanthanum Fluoride, bụ nke etinyere na iko ọpụrụiche, ọgwụgwọ mmiri na ihe na-akpali akpali, yana dịkwa ka isi akụrụngwa maka ịme Lanthanum Metal. Lanthanum fluoride (LaF3) bụ akụkụ dị mkpa nke iko Fluoride dị arọ aha ya bụ ZBLAN. Iko a nwere nnyefe dị elu na oke infrared ma ya mere eji ya maka usoro nkwurịta okwu fiber-optical. A na-eji Lanthanum Fluoride mee ihe na mkpuchi phosphor. Ejikọtara ya na Europium Fluoride, a na-etinyekwa ya na akpụkpọ anụ kristal nke Fluoride ion-selective electrodes.A na-eji Lanthanum fluoride akwadebe scintilators na ihe laser kristal na-adịghị ahụkebe nke teknụzụ ihe ngosi ahụike ọgbara ọhụrụ na sayensị nuklia chọrọ. A na-eji Lanthanum fluoride mee ka fluoride enyo fiber optical na iko infrared ụwa na-adịghị ahụkebe. A na-eji Lanthanum fluoride na-emepụta arc lamp carbon electrodes na isi mmalite ọkụ. A na-eji Lanthanum fluoride na nyocha kemịkalụ iji rụpụta ion fluoride electrodes.

Usoro sịntetik
1. Gbanyụọ lanthanum oxide na hydrochloric acid site na usoro kemịkalụ wee gbasaa ruo 100-150g/L (gbakọrọ dị ka La2O3). Kpoo ihe ngwọta ahụ ruo 70-80 ℃, wee gbanye ya na 48% hydrofluoric acid. A na-asachapụ mmiri ozuzo, kpochaa, akpọnwụọ, gwepịara ya, wee kpoo mmiri iji nweta lanthanum fluoride.
2. Debe ngwọta LaCl3 nwere hydrochloric acid na efere platinum ma tinye 40% hydrofluoric acid. Wunye oke mmiri mmiri wee kpochapụ ihe fọdụrụnụ.
