Multilingual: YttriumOxalat, Oxalate De Yttrium, Oxalate Del Ytrio		 Yttrium Oxalate is applied in ceramics, glass, and electronics. 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 Oxalate is highly insoluble in water and converts to the Oxide when heated (calcined). Yttrium is used in the production of a large variety of synthetic garnets, and yttria is used to make Yttrium-Iron-Garnets, which are very effective microwave filters.
