Indium Tin Oxide (ITO)

Indium tin oxide (ITO, or tin-doped indium oxide) is a mixture of indium(III) oxide (In₂O₃) and tin(IV) oxide (SnO₂) (90% In₂O₃: 10% SnO₂ by weight).
Indium tin oxide (ITO) is a yellow-green powder but transparent and colorless when deposited as a thin film (thicknesses of 1000-3000 angstroms). It is one of the most widely used transparent conducting oxides due to the combination of its electrical conductivity and optical transparency, the ease with which it can be deposited as a thin film, and its chemical resistance to moisture. Thin films of indium tin oxide are deposited by electron beam evaporation or a range of sputter deposition techniques, or other forms of physical vapor deposition.

Typical Purity: 99.99% (metals basis)
Typical Applications

ITO is used in several display technologies, such as LCD, OLED, plasma, electroluminescent, and electrochromic displays, as well as in several touch screen technologies. Other uses of ITO include antistatic indium tin oxide coatings, EMI shielding, photovoltaic solar cells, aircraft windshields, freezer case glass for demisting, and heat-reflecting mirrors.
