Yttrium Fluoride 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.
Yttrium Fluoride also can be used for the production of metallic Yttrium, thin films, glasses and ceramics.
Yttrium is used in the production of a large variety of synthetic garnets, and Yttria is used to make Yttrium Iron Garnets, which are very effective microwave filters.
