It's not a real compound
The chemical formulasof indium oxides are InOand In2O3.
The code is ITO (but this is not a true chemical formula); this is a mixture of In2O3 and SnO2.
Indium is a stable metal under normal conditions, meaning it does not spontaneously react with air or water. However, it is susceptible to oxidation when exposed to air over time, forming a dull oxide layer on its surface.
Indium bond with lots of elements to form compounds. Examples: Indium + Phosphorus --> Indium Phosphide Indium + Bromine --> Indium (I/III) Bromide Indium + Fluorine --> Indium Fluoride Indium + Oxygen --> Indium Oxide Indium + Antimony --> Indium Antimonide Indium + Arsenic --> Indium Arsenide
No, indium does not rust because it is a corrosion-resistant metal. Rusting typically occurs in iron and steel due to the reaction of iron with oxygen and water, forming iron oxide. Indium, on the other hand, does not undergo the same chemical reaction with oxygen and water that leads to rusting.
Generally speaking it does not form compounds with metals. Indium forms compounds with practically all of the non metals. It forms alloys with some metals, it even has been found to form a strange compound with potassium which contains a polymeric indium anion.
Indium forms the following bromides InBr3, indium tribromide, indium (III) bromide InBr, Indium monobromide, Indium(I) bromide InBr2, indium dibromide, In+ InBr4- , indium (I,III) bromide there are others which are not so well known

ITO, a mixture of indium oxide In2O3 (90 %) and SnO2 (10 %) is largely used for displays coatings being transparent and electrically conductive. Also used in solar cells, glasses for sodium vapor lamps, infrared mirrors, etc. The metal is used in some alloys, coating for bearings as lubricant, control rods for nuclear reactors (alloy Ag-In-Cd) etc. See the link below for more information. Indium is also used as an N type dopant in some semiconductor devices (the corresponding P type dopant is Antimony).
The chemical formula of calcium oxide is CaO.
Fe2O3 is Iron 3 oxide
