Indium-Tin Oxide (ITO)
In2O3: SnO2Introduction
Indium-tin oxide (ITO, or tin-doped indium oxide) is a
mixture of indium(III) oxide (In 2 O 3 ) and tin(IV) oxide(SnO 2 ), typically 90% In2 O 3 , 10% SnO 2 by weight.

Standard ITO• Primary particles are regularly shaped ranging in size from0.4 to 1.0µm• Agglomerates in size up to approximately 31µm

In powder form it is yellow-green in color, but it istransparent and colorless when deposited as a thin film
at thicknesses of 50–300nm. When deposited as a thinfilm on glass or clear plastic, it functions as a transparent
electrical conductor.
ITO is normally deposited by a physical vapor deposition
process such as D.C. magnetron sput tering orelectron beam deposition. Less frequently, ITO can beincorporated in inks using an appropriate film-forming
polymer resin and solvent system, and deposited byscreen printing albeit with lower transparency andconductivity compared to a physical deposition process.
Of the various transparent conductive oxides (TCOs),
ITO is considered the premium TCO, having superior
conductivity and transparency, stability, and ease ofpatterning to form transparent circuitry.
ITO is used in both LCDs and OLED displays, as well asin plasma, electroluminescent, and electrochromatic
displays. It is also utilized in touch panels, antistatic
coatings, EMI shielding, aircraft windshields, freezer-caseglass for demisting, and photovoltaic solar cells. A further
use is as an IR-coating to reflect heat energy, such as in
low-E glass and in low-pressure sodium lamps.

Fine ITO• Primary particles are regularly shaped ranging in size from
0.1 to 1.0µm• Agglomerates in size up to approximately 7µm

Indium Corporation uses a proprietary process to manufacture
co-precipitated ITO powder of high purity. This processachieves tin-doping at customer-specified levels throughactual substitution of tin in the indium oxide crystal lattice.
Our experience in process engineering enables us tomanufacture ITO powder with a close tolerance particle size
distribution, tap density, and BET properties. This enables
our customers to manufacture high-quality, high-density ITO
sputtering targets and electron beam deposition sources.

Powder Description
The powder morphology or grain structure of ITO varies slightly
with the level of tin-doping. The morphology represented in thisproduct data sheet is typical for a 10.0 weight percent SnO 2
equivalent doping level.
