Yttrium Fluoride

Yttrium fluoride is colorless cubic crystalline powder, which is made from yttrium oxide. Yttrium fluoride stay stable under room temperature and pressure. It is insoluble in water and difficult to dissolve hydrochloric acid, nitric acid and sulfuric acid. However it is soluble in perchloric acid. When in air, yttrium fluoride absorb moisture but stable. It compounded with ammonium fluoride to get insoluble doulble salt NH4F.YF3.
