Applicatio:

Lanthanum Fluoride, praesertim in specialitate vitri, aquae curationis et catalysti applicatur, nec non sicut materias crudas praecipuas ad Lanthanum Metallum conficiendum. Lanthanum Fluoride (LaF3) est elementum essentiale vitri Fluoride gravi nomine ZBLAN. Hoc vitrum superius transmissio in ultrarubrum eminet et ideo ad systemata communicationis optica adhibenda est. Lanthanum Fluoride adhibetur in phosphoro lampade coatings. Mixta cum Europio Fluoride, applicatur etiam in membrana crystalli Fluoride electrodes ion-selectivae.Lanthanum fluoride adhibetur ad scintillatores praeparandos et materias laser crystalli raras quae a modernis medicalis imaginem technologiam et scientiam nuclearem exhibent. Lanthanum fluoride adhibetur ad fibra vitrea fluoride optica et rara terrae vitri infrarubrum. Lanthanum fluoride adhibetur in fabricandis arcus lampadis carbonis electrodes in fontibus illustrandis. Lanthanum fluoride usus est in analysi chemica ad electrodes selectivam fabricandi fluoride ion.

Synthetica methodo

1. Lanthanum oxydatum solve in acido hydrochlorico methodo chemica et diluto ad 100-150g/L (pro La2O3). Calefacere solutionem 70-80 , et tunc praecipitare cum acido hydrofluorico 48%. Praecipitatio lota, percolata, siccata, contusa, et vacuum dehydratum ob- lanthanum fluoride.

2. Loco LaCl3 solutionem acidum hydrochloricum in patina platini continentem et 40% acidum hydrofluoricum adde. Liquidum superfluum effunde et residuum siccum evaporate.
