Atomic No. 39 Y Yttrium

About Yttrium

Yttrium is a transition metal with atomic number 39 that is commonly grouped with the rare earth elements and predominantly forms +3 compounds. Yttrium aluminum garnet is a host for laser materials and phosphors, with its optical function determined by the incorporated dopants. Yttrium fluoride is used in protective coatings for semiconductor processing equipment exposed to corrosive plasmas. Yttrium tantalate provides another specialized application as a phosphor material for X ray imaging.
