INDIUM HYDROXIDE Usage And Synthesis

General Description

Indium hydroxide (In(OH)3) is a white powder that is available in two morphologies: crystalline and fine powder. It is soluble in mineral acids but insoluble in water.
The crystalline powder has cubic shaped crystals with a size range of 1 to 5 &mu;m.
The fine powder has smaller primary particles (0.1 to 1.0 &mu;m) with a range of shapes (spherical to elliptical).
Indium hydroxide is used in a variety of industries, including the manufacturing of flat panel components.

Chemical Properties

yellow-white powder(s); -100 mesh with 99.999% purity [AES93] [CER91]

Uses

Indium(III) hydroxide is used as a precursor to indium(III)oxide. It is also applied in batteries, glasses, ceramics, chemical reagents and semiconductors.

Preparation

According to Milligan and Weiser, a small excess of NH3 solution is added at 100℃ to an InCl3 solution. The precipitate is aged a few hours at 100℃ by letting it stand under its mother liquor, then washed free of chloride and dried at room temperature.

reaction suitability

reagent type: catalyst
core: indium
