Yttrium Oxide Powder (Y2O3), CAS 1314-36-9
Yttrium oxide powder (Y2O3) is a white, odorless powder that is commonly used as a raw material for the production of other yttrium compounds, such as yttrium metal, yttrium fluoride, and yttrium nitrate.
Yttrium oxide is insoluble in water, but soluble in acids. It has a high melting point of 2,410 °C and a high thermal conductivity, making it useful in high-temperature applications. It is also used as a phosphor in television tubes, as a component in the production of high-strength ceramics, and as a catalyst in various chemical reactions.
Yttrium oxide powder should be stored in a cool, dry place, away from heat sources and incompatible materials. Proper protective equipment, such as gloves and safety goggles, should be worn when handling this material.

Application
Yttrium Oxide also called Yttria, high purity Yttrium Oxides are the most important materials for tri-bands Rare Earth phosphors which give the red color in color television & computer tubes. In the optical industry, the Yttrium Oxide is used to produce Yttrium-Iron-Garnets, which are very effective microwave filters. Low purity of Yttrium Oxide is widely applied in electronic ceramics. It is widely used to make Eu: YVO4 and Eu: Y2O3 phosphors that give the red color in color TV picture tubes. Yttrium Oxide is also used to make Yttrium-Iron-Garnets, which are very effective microwave filters.
