The precipitation of indium hydroxide was a step in the separation of indium from zincblende ore by Reich and Richter, the discoverers of indium. [6] 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), [5] having a lower ...
InCl 3 (structure pictured) is a common compound of indium. Indium(III) oxide, In 2 O 3, forms when indium metal is burned in air or when the hydroxide or nitrate is heated. [38] In 2 O 3 adopts a structure like alumina and is amphoteric, that is able to react with both acids and bases.
Bulk samples can be prepared by heating indium(III) hydroxide or the nitrate, carbonate or sulfate. [9] Thin films of indium oxide can be prepared by sputtering of indium targets in an argon/oxygen atmosphere. They can be used as diffusion barriers ("barrier metals") in semiconductors, e.g. to inhibit diffusion between aluminium and silicon. [10]
There are three sets of Indium halides, the trihalides, the monohalides, and several intermediate halides. In the monohalides the oxidation state of indium is +1 and their proper names are indium(I) fluoride, indium(I) chloride, indium(I) bromide and indium(I) iodide. The intermediate halides contain indium with oxidation states, +1, +2 and +3.

Dzhalindite is a rare indium hydroxide mineral discovered in Siberia.Its chemical formula is In(OH) 3.. It was first described in 1963 for an occurrence in the Dzhalinda tin deposit, Malyi Khingan Range, Khabarovskiy Kray, Far-Eastern Region, Russia.

The hydroxide ion is naturally produced from water by the self-ionization reaction: [2] H 3 O + + OH − ⇌ 2H 2 O. The equilibrium constant for this reaction, defined as K w = [H +][OH −] [note 1] has a value close to 10 −14 at 25 °C, so the concentration of hydroxide ions in pure water is close to 10 −7 mol∙dm −3, to satisfy the ...
