Ntchito:
Lanthanum Fluoride, amagwiritsidwa ntchito makamaka mu galasi lapadera, chithandizo cha madzi ndi chothandizira, komanso ngati zipangizo zazikulu zopangira Lanthanum Metal.Lanthanum Fluoride (LaF3) ndi gawo lofunikira la galasi lolemera la Fluoride lotchedwa ZBLAN.Galasi ili ndi ma transmittance apamwamba kwambiri pamtundu wa infrared motero amagwiritsidwa ntchito pamakina olumikizirana ndi fiber-optical.Lanthanum Fluoride imagwiritsidwa ntchito popaka nyali za phosphor.Kusakaniza ndi Europium Fluoride, imagwiritsidwanso ntchito mu crystal nembanemba ya Fluoride ion-selective electrodes.Lanthanum fluoride imagwiritsidwa ntchito popanga ma scintillators ndi zida za laser zapadziko lapansi zomwe zimafunikira ndiukadaulo wamakono wowonetsa zithunzi zachipatala ndi sayansi ya nyukiliya.Lanthanum fluoride imagwiritsidwa ntchito popanga magalasi a fluoride optical fiber ndi magalasi osowa padziko lapansi.Lanthanum fluoride imagwiritsidwa ntchito popanga ma elekitirodi a kaboni a arc muzowunikira.Lanthanum fluoride yomwe imagwiritsidwa ntchito posanthula mankhwala kupanga ma electrode osankhidwa a fluoride ion.

Njira yopangira
1. Sungunulani lanthanum okusayidi mu hydrochloric acid ndi njira mankhwala ndi kuchepetsa kwa 100-150g/L (kuwerengeredwa monga La2O3).Kutenthetsa njira 70-80 ℃, ndiyeno mpweya ndi 48% hydrofluoric acid.Mvula imatsukidwa, kusefedwa, kuuma, kuphwanyidwa, ndi kupukuta madzi kuti apeze lanthanum fluoride.
2. Ikani njira ya LaCl3 yokhala ndi hydrochloric acid mu mbale ya platinamu ndikuwonjezera 40% ya hydrofluoric acid.Thirani madzi owonjezera ndikusungunula zotsalirazo zouma.
