Application

Lanthanum Fluoride, is mainly applied in specialty glass, water treatment and catalyst, and also as the main raw materials for making Lanthanum Metal. Lanthanum Fluoride (LaF3) is an essential component of a heavy Fluoride glass named ZBLAN. This glass has superior transmittance in the infrared range and is therefore used for fiber-optical communication systems. Lanthanum Fluoride is used in phosphor lamp coatings. Mixed with Europium Fluoride, it is also applied in the crystal membrane of Fluoride ion-selective electrodes.
