Yttrium Fluoride

Yttrium fluoride is white powder which insoluble in water, hardly soluble in hydrochloric acid, nitric acid and sulfuric acid. But it is soluble in perchloric acid. It is hardly absorb moisture in air, stable.

Applications:

Yttrium fluoride is widely used as optical material.

It is widely applied in metallurgy, ceramics, glass, and electronics.

High purity grades are the most important materials for tri-bands Rare Earth phosphors and , which are very effective microwave filters.

It also can be used for the production of metallic Yttrium, thin films, glasses and ceramics.
