Yttrium Oxide Application

1: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.

2:In optical industry, the Yttrium Oxide is used to produce Yttrium-Iron-Garnets, which are very effective microwave filters.

3: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.

4:Yttrium Oxide is also used to make Yttrium-Iron-Garnets, which are very effective microwave filters.
