Indium sulfate Usage And Synthesis

General Description

Indium sulfate (In2(SO4)3) is a grayish-white powder. It is hydroscopic and has a monoclinic crystal structure. It is available in several forms, i.e. as an anhydrous powder, as a hydrated salt with 9 moles of associated water, and as a solution in varying concentrations in water, up to its solubility limit.

Chemical Properties

Grayish powder. Deliquescent. Soluble in water. Decomposed by heat.

Uses

Indium sulfate has a very limited use.

Uses

Indium(III) sulfate is used Chemical synthesis, hardening agent in gold electroplating baths. It is also used to prepare other indium containing substances such as copper indium selenide.

Hazard

See indium; tellurium.

reaction suitability

reagent type: catalyst
core: indium

Purification Methods

Crystallise it from dilute aqueous H2SO4. It is hygroscopic; store it in a well-stoppered vessel.
