Yttrium Carbonate 99.99% is mainly used for optical glass. High purity grades are the most important materials for tri-bands Rare Earth phosphors and Yttrium-Iron-Garnets, which are very effective microwave filters. Yttrium Carbonate is a water insoluble Yttrium source that can easily be converted to other Yttrium compounds, such as the Oxide by heating (calcination).
