YTTRIUM SULFATE OCTAHYDRATE Usage And Synthesis
UsesYttrium Sulfate, also called Yttrium Sulphate, is applied in ceramics, glass, and electronics. Yttrium Sulfate is a moderately water and acid soluble Yttrium source for uses compatible with sulfates. 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.
Chemical PropertiesSmall, reddish-white, monosymmetric crystals. D 2.558, loses 8H2O at 120C, decomposes 700C. Soluble in concentrated sulfuric acid; sparingly soluble in water; insoluble in alkalies.
Physical propertiesRed monoclinic crystals; density 2.59 g/cm3; loses all its water molecules at 120°C; decomposes at 700°C; sparingly soluble in water, less soluble in hot water; dissolves in concentrated sulfuric acid forming Y(HSO4)3; insoluble in alkalis; forms double salts with alkali sulfates.
UsesYttrium(III) sulfate octahydrate is used as a laboratory reagent, colorant, structural ceramics, optical glasses and catalysts. It finds application in electrical components and photo-optical materials.
usesYttrium sulfate is used in making many yttrium salts.
PreparationYttrium sulfate is produced as an intermediate in recovering yttrium from monazite or xenotime (see Yttrium, Recovery). Rare earth sulfates are separated on a cation exchange resin bed. Yttrium fraction is purified by fractional crystallization. Alternatively, yttrium sulfate may be prepared by reacting yttrium oxide with sulfuric acid.
