Use：: Yttrium Oxide, also called Yttria, high purity Yttrium Oxides are the most important materials for tri-bands Rare Earth phosphors which give the red colour in colour television computer tubes. In optical industry, the Yttrium Oxide is used to produce Yttrium-Iron-Garnets, which are very effective microwave filters. Low purity of Yttrium Oxide are 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. Also, it is used in gas mantles and acetylene lights. Other uses are in yttriumiron garnets for microwave filters in lasers, and as a stabilizer for high temperature in refractories.
