Indium-Tin Oxide (ITO) 97550 R12
Indium-tin oxide (ITO, or tin-doped indium oxide) is a mixture of indium(III) oxide (In2O3) and tin(IV) oxide (SnO2), typically 90% In2O3, 10% SnO2 by weight. In powder form it is yellow-green in color but it is transparent and colorless when deposited as a thin film at thicknesses of 1,000 3,000 angstroms.
