Yttrium(III) oxide 99,99% – Er2O3 – 5.0 grams

High pure Yttrium(III) oxide 99,99% 5 grams
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.
Melting point: 2410 Grad C.
Its easy to produce other Yttrium compounds with this material.
