Lanthanum Fluoride LaF3 used for required modern medical image
Lanthanum fluoride is a white powder insoluble in water, insoluble
in hydrochloric acid, nitric acid and sulfuric acid, but soluble in
perchloric acid. Stable in air. Ammonium fluoride produces NH4FLaF3
insoluble double salt.The preparation method is to add hydrofluoric
acid to lanthanum salt solution, or to prepare hydrated lanthanum
fluoride from lanthanum hydroxide and hydrofluoric acid, and then
to get lanthanum fluoride by vacuum heating.
【Application】
1.It is suitable for ceramics manufacturing.
2.It is resistant to many reactive molten metals such as titanium
or uranium.
3.For producing of multilayer ceramic capacitors, Lanthanum fluoride is also employed as a dopant to reduce the Curie temperature of the
barium titanate substrate due to its special properties.
