Description

Yttrium Oxide, also called Yttrium (III) oxide and Yttria, is a white solid substance which is stable in air. 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. Yttrium Oxide is also used to make Yttrium-Iron-Garnets, which are very effective microwave filters.
