ITO Indium tin oxide or Indium doped tin oxide is a ternary composition of different indium, tin, and oxygen ratios. According to the oxygen content, it can be described as ceramic or alloy. Usually encountered in indium tin oxide as an oxygen-saturated composition, its formulation is 74% In, 18% O2, and 8% Sn by weight. Oxygen-saturated compositions are so typical that unsaturated compositions are referred to as oxygen-deficient ITO. The thin layer is transparent and colorless, and the bulk is a pale yellow to gray. In the infrared region of the spectrum, it acts like a metal mirror.

Indium tin oxide is one of the most widely used transparent conductive oxides because of its electrical conductivity, optical transparency, and ease with which it is deposited as a thin film. As with all transparent conductive films, a compromise must be made between conductivity and transparency because increasing the thickness and concentration of charge carriers will increase the film's conductivity but will reduce its transparency.

Indium tin oxide films are most commonly deposited by physical vapor deposition on the surface. Usually, electron beam evaporation or a series of sputtering deposition techniques are used.

ITO is a mixed oxide of indium and tin. Depending on the composition, its melting point is in the range of 1526-1926°C. The composition of the most commonly used material is ca In4Sn. This material is an n-type semiconductor with a large bandgap of about 4 eV. ITO is transparent to visible light and has relatively high electrical conductivity. These features have great advantages in touch screen applications such as mobile phones.

Performance of Indium Tin Oxide ITO Powder:

Chemically, ITO is the abbreviation of Indium Tin Oxides.

As a nano-indium tin metal oxide, it has good conductivity and transparency and can reduce harmful electronic radiation, ultraviolet and far-infrared rays. Therefore, indium tin oxide is sprayed on glass, plastic, and electronic display screens and used as a transparent conductive film while reducing harmful electronic radiation and ultraviolet and infrared.

In the oxide conductive film, the Sn-doped In2O3 (ITO) film has the highest transmittance and the best conductive performance, and it is easy to etch fine patterns in the acid solution, of which the light transmittance is more than 90%. The transmittance and resistance of ITO are controlled by the ratio of In2O3 and SnO2, usually SnO2:In2O3=1:9.

How is Indium Tin Oxide ITO Powder produced?
Solid phase synthesis method:
The solid phase synthesis method mixes indium and tin oxides or other compounds according to a certain proportion and reacts at high temperatures to produce indium tin oxide. The reaction equation is:
In2O3(s) + SnO2(s) → ITO(s)
The solid phase synthesis method has the advantages of a simple process and low production cost, but the product purity is low and needs to be washed and refined several times.
Gas phase synthesis method:
The gas phase synthesis method produces indium tin oxide by gas reaction of indium and tin oxide under oxygen or air atmosphere at high temperature. This method has the advantages of high product purity and chemical activity. Still, it must use high-purity indium and tin as raw materials, and the production cost is high.
Solution synthesis method:
The solution synthesis method is to add an appropriate amount of oxidant or other reactants containing indium and tin ions to oxidize indium and tin ions to produce indium-tin oxide. This method has the advantages of high product purity and a simple process, but it needs to be washed and dried several times.
Chemical vapor deposition method:
Chemical vapor deposition (CVD) is the thermal decomposition or chemical synthesis of ITO films on the substrate. This method has the advantages of high product purity and adjustable film thickness, but it needs special equipment and technology, and the production cost is high.
Sputtering method:
The sputtering method uses glow discharge or ion beam sputtering technology to sputter indium and tin targets onto the substrate to produce indium tin oxide thin films. This method has the advantages of high product purity and strong film adhesion, but it needs to use equipment and power supply with high vacuum degrees, and the production cost is high.

 

Applications of Indium Tin Oxide ITO Powder:

Indium tin oxide (ITO) is an optoelectronic material widely used in research and industry. ITO can be used in many applications, such as flat panel displays, smart windows, polymer-based electronics, thin-film photovoltaic products, glass doors for supermarket freezers, and architectural windows. Also, the ITO film used for the glass substrate helps the glass window save energy.

The ITO belt is used to produce electroluminescent, fully functional, and fully flexible lamps. Besides, the ITO film is mainly used as an anti-reflective coating. It is used in liquid crystal displays (LCD) and electroluminescence, where the film is used as a conductive transparent electrode.

ITO is commonly used to make transparent conductive coatings for displays (such as liquid crystal, OLED, plasma, touch panels, and electronic ink applications). ITO film is also used for organic light-emitting diodes, solar cells, antistatic coatings, and EMI shielding. ITO is used as the anode (hole injection layer) in organic light-emitting diodes.

ITO-coated glass (indium tin oxide glass) belongs to the TCO (transparent conducting oxide) conductive glass category. ITO glass has the characteristics of low sheet resistance and high light transmittance. 

 

The ITO film deposited on the windshield defrosts the aircraft's windshield. Heat is generated by applying a voltage to the film.

 

ITO coating: ITO is also used in various optical coatings, the most famous being infrared reflective coatings (hot mirrors) used in automobiles and sodium vapor lamp glass. Other uses include gas sensors, anti-reflective coatings, electrowetting on dielectrics, and Bragg reflectors for VCSEL lasers. ITO is also used as an infrared reflector for low-emissivity window panes. Starting with the Kodak DCS 520, later, Kodak DCS cameras also used ITO as a sensor coating to enhance the response of the blue channel.

ITO thin film strain gauges can operate at temperatures up to 1400°C and be used in harsh environments such as gas turbines, jet engines, and rocket engines.
