YTTRIUM SULFATE OCTAHYDRATE Chemical Properties,Usage,Production

Uses

Yttrium 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.

Description

Yttrium(III) sulfate octahydrate, with the chemical formula Y2(SO4)3-8H2O, consists of infinite layers parallel to (10\overline 1), with [Y(H2O)4(SO4)3/2] being the only repeating unit. The layers are connected to each other using only moderately strong hydrogen bonds. The trivalent yttrium cation is coordinated by eight O-atoms from four sulfate groups and four water molecules in a distorted square antitetrahedron [YO8]. It is of the same structural type as the rare earth sulfate octahydrate[1].

Figure 1. View perpendicular to the (10 1) layer of the title compound, with [Y(H 2 O) 4/1 (SO 4 (1)) 3/3 (SO 4 (2)) 1/2 ] as the repeat unit. Key: [SO 4 ] tetrahedra (yellow), [YO 8 ] antiprisms (red), oxygen (blue) and hydrogen (light grey) atoms.

Chemical Properties

Small, 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 properties

Red 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.

Uses

Yttrium(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.

Uses

Yttrium sulfate is used in making many yttrium salts.

Preparation

Yttrium 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.
