Indium(III) hydroxide is the chemical compound with the formula In(OH)3. Its prime use is as a precursor to indium(III) oxide, In2O3.

 Indium oxide is used in batteries, transparent thin film infra-red reflectors. It is also commonly doped with tin oxide (SnO2) to make indium tin oxide (ITO), which is used in transparent thin conductive thin films, which are used in various different types of displays, energy efficient windows and photovoltaics.

 Indium(III) oxide (In2O3) is a chemical compound, an amphoteric oxide of indium.

 Indium(III) hydroxide is amphoteric, like gallium(III) hydroxide (Ga(OH)3) and aluminium hydroxide (Al(OH)3), but is much less acidic than gallium hydroxide (Ga(OH)3), having a lower solubility in alkaline solutions than in acid solutions. It is for all intents and purposes a basic hydroxide.

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

 An FDA-approved prescription drug, called indium (In-111) pentetreotide, is used by healthcare professionals to find certain tumors inside the body. It is given by IV.

 Indium is used in many high-tech devices such as touch screens, smart phones, solar panels and smart windows, in the form of indium tin oxide. This compound is optically transparent and electrically conductive — the two crucial features required for touch screens to work.

 Physical properties Amorphous indium oxide is insoluble in water but soluble in acids, whereas crystalline indium oxide is insoluble in both water and acids.
