InCl can be prepared by heating indium metal with indium trichloride in a sealed tube. [3] [4]According to X-ray crystallography, the structure of the yellow polymorph resembles that of sodium chloride except that the Cl-In-Cl angles are not 90°, but range between 71 and 130°.
Indium oxide is used in some types of batteries, thin film infrared reflectors transparent for visible light (hot mirrors), some optical coatings, and some antistatic coatings. In combination with tin dioxide, indium oxide forms indium tin oxide (also called tin doped indium oxide or ITO), a material used for transparent conductive coatings.
Indium antimonide (InSb) is a crystalline compound made from the elements indium (In) and antimony (Sb). It is a narrow- gap semiconductor material from the III - V group used in infrared detectors , including thermal imaging cameras, FLIR systems, infrared homing missile guidance systems, and in infrared astronomy .
The indium chalcogenides include all compounds of indium with the chalcogen elements, oxygen, sulfur, selenium and tellurium. ( Polonium is excluded as little is known about its compounds with indium).
These tables list values of molar ionization energies, measured in kJ⋅mol −1.This is the energy per mole necessary to remove electrons from gaseous atoms or atomic ions.
Indium(II) selenide (InSe) is an inorganic compound composed of indium and selenium. It is a III-VI layered semiconductor. The solid has a structure consisting of two-dimensional layers bonded together only by van der Waals forces. Each layer has the atoms in the order Se-In-In-Se. [2]
Indium sulfate is a commercially available chemical. It can be used to electroplate indium metal, [50] as a hardening agent in gold electroplating [51] or to prepare other indium containing substances such as copper indium selenide. It has been sold as a health supplement, even though there is no evidence of benefit to humans, and it is toxic. [52]
The hydrate first decomposes to a basic salt and then to indium(III) oxide at 240 °C. Anhydrous indium(III) nitrate is claimed to be produced by the reaction of anhydrous indium(III) chloride and dinitrogen pentoxide. [2] [4] In the presence of excess nitrate ions, indium(III) nitrate converts to the [In(NO 3) 4] − ion. [1] [2]
