Indium Tin Oxide

Indium Tin Oxide (ITO) is a transparent conductive oxide that is widely used in various industries due to its unique properties. It is a mixture of indium oxide and tin oxide in varying proportions, usually with a ratio of 90:10 or 95:5. ITO is a transparent, colorless material with a high electrical conductivity and is optically transparent in the visible range of the electromagnetic spectrum.

Features:

The primary features of ITO include its high electrical conductivity, optical transparency, and excellent mechanical and chemical stability. It is an excellent conductor of electricity and can be used to create transparent conductive coatings for a wide range of applications. ITO also has excellent thermal stability, making it suitable for use in high-temperature applications.

Grades:

ITO is available in different grades depending on the application. The most common grades are high-purity ITO, nano-ITO, and low-resistance ITO. High-purity ITO is used for applications that require high transparency, while nano-ITO is used for applications that require high conductivity. Low-resistance ITO is used for applications that require high conductivity and low resistance.

Forms:

ITO is available in different forms, including thin films, sputtering targets, and powder. Thin films are the most commonly used form of ITO and are used for applications such as touch screens and flat panel displays. Sputtering targets are used to produce ITO coatings on glass and other substrates. ITO powder is used for applications that require the creation of custom coatings.

Specifications of ITO Thin Films:

● Thickness: The thickness of ITO thin films varies depending on the application, but typically ranges from a few nanometers to a few micrometers.

● Sheet Resistance: The sheet resistance of ITO thin films is typically in the range of 10-500 ohms/square.

● Optical Transmission: ITO thin films have high optical transparency in the visible range of the electromagnetic spectrum, typically above 80%.

Specifications of ITO Sputtering Targets:

● Purity: ITO sputtering targets are available in high purity grades ranging from 99.9% to 99.999% purity.

● Shape and Size: ITO sputtering targets are available in various shapes and sizes, including discs, rectangular plates, and custom shapes.

● Density: The density of ITO sputtering targets typically ranges from 6.6 to 7.2 g/cm3.

Specifications of ITO Powder:

● Purity: ITO powder is available in high purity grades ranging from 99.9% to 99.999% purity.

● Particle Size: ITO powder is available in different particle sizes, typically ranging from 0.5 to 5 microns.

● Specific Surface Area: The specific surface area of ITO powder is typically in the range of 5 to 50 m2/g.

Production Method:

ITO is usually produced by sputtering or electron beam evaporation. In sputtering, a target made of indium and tin is bombarded with ions, releasing atoms that deposit onto a substrate to form an ITO film. In electron beam evaporation, a target is heated and evaporated in a vacuum, and the resulting vapor deposits onto a substrate to form an ITO film.

Applications & Related Industries:

ITO is used in a wide range of applications, including touch screens, flat panel displays, solar cells, and electronic devices. It is also used in the automotive industry for antifogging and defrosting windows. Other industries that use ITO include aerospace, military, and telecommunications.

Health & Safety Information:

ITO is generally safe to handle, but it is important to follow proper safety precautions when working with it. It is recommended to wear gloves, a lab coat, and safety glasses when handling ITO. Additionally, ITO should be handled in a well-ventilated area to avoid inhalation of dust.
