Indium Tin Oxide ITO Powder

About Indium Tin Oxide ITO Powder:
Indium tin oxide (ITO) is a ternary composition of different ratios of indium, tin and oxygen. According to the oxygen content, it can be described as ceramic or alloy. Usually encountered 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 and optical transparency and the 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 increasing the concentration of charge carriers will increase the conductivity of the film, but will reduce its transparency.
 
Indium tin oxide films are most commonly deposited on the surface by physical vapor deposition. 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 cut off harmful electronic radiation, ultraviolet rays and far-infrared rays. Therefore, indium tin oxide is usually sprayed on glass, plastic and electronic display screens, 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?
The ITO powder usually adopts the following preparation method: respectively oxidizing metal indium and metal tin to obtain indium oxide powder and tin oxide powder and then mixing and dispersing the indium oxide powder and tin oxide powder. In this method, it is difficult to completely synchronize the control conditions such as metal indium and metal tin as the basic raw material, such as the dissolution rate, dissolution temperature, neutralization pH value, neutralization temperature, and stirring speed, so the prepared indium oxide powder, The particle size deviation of tin oxide powder is large, which affects the quality of ITO film. In order to solve the problem of the uniformity of ITO powder, the co-precipitation method is also used to produce ITO powder. This method uses nitric acid to dissolve metal indium and metal tin, and then mix the resulting indium nitrate and tin nitrate according to the ratio, and then use ammonia to co-precipitate. Precipitation to obtain co-precipitated hydroxide, and finally, calcination to obtain indium tin oxide.
 
Applications of Indium Tin Oxide ITO Powder:
Indium tin oxide (ITO) is an optoelectronic material that has been 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 to save energy.
 
The ITO green belt is used to produce electroluminescent, fully functional and fully flexible lamps. Besides, the ITO film is mainly used as an anti-reflective coating and 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 displays, OLED displays, plasma displays, touch panels, and electronic ink applications). ITO film is also used for organic light-emitting diodes, solar cells, antistatic coatings and EMI shielding. In organic light-emitting diodes, ITO is used as the anode (hole injection layer).
 
The ITO film deposited on the windshield is used to defrost the windshield of the aircraft. Heat is generated by applying a voltage to the film.
 
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 can be used in harsh environments such as gas turbines, jet engines and rocket engines.
