Application:

Yttrium's most important use is in making phosphors which are used in CRT displays and in LEDs. Yttrium is also used in the production of superconductors, electrodes, electrolytes, electronic filters, and lasers. Yttria stabilized zirconium oxide is used in high temperature applications, such as in thermal plasma sprays to protect aerospace high temperature surfaces. High Purity (99.999%) Yttrium Oxide (Y2O3) PowderCrystals of the yttrium-iron-garnet (YIG) variety are essential to microwave communication equipment and yttrium-aluminum-garnet (YAG) crystals are used as laser gain media. High Purity (99.999%) Yttrium (Y) Sputtering TargetYttrium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity). Metallic forms include pellets, rod, wire and granules for evaporation source material purposes. Yttrium nanoparticles and nanopowders provide ultra-high surface area. Yttrium oxides is available in powder and dense pellet form for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Yttrium is also available in soluble forms including yttrium chloride, nitrate and acetate. These compounds can be manufactured as solutions at specified stoichiometries.
