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.

| Questions And Answer | Back Directory | [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 μm.
The fine powder has smaller primary particles (0.1 to 1.0 μm) with a range of shapes (spherical to elliptical).
Indium hydroxide is used in a variety of industries, including the manufacturing of flat panel components.
