Ⅰ、Semiconductor Industry

Indium is a rare metal element that is widely used in the semiconductor industry as an inclusion element added to purified silicon to improve the electron mobility of silicon. Indium is widely used in the manufacture of semiconductors, such as the manufacture of high electron mobility transistors, photoelectric devices, solar cells and so on. In addition, indium doping can also be used to produce high-speed, high-efficiency computer chips.

Ⅱ、Liquid Crystal Display Industry

Indium-doped indium oxide (ITO) is a commonly used conductive material and is widely used in liquid crystal displays. The higher the amount of indium doped in ITO, the better the conductivity. ITO conductive films are widely used in the electrodes of liquid crystal displays to connect circuits and control the deflection and color of liquid crystals. In addition, indium-doped indium oxide can also be used as a transparent electrothermal film and electrode for solar cells.

Ⅲ、Nanotechnology

With the continuous development of nano science and technology, indium is more and more widely used. Indium is an important nanoparticle doping element, which is used in the synthesis of transparent conductive materials, the production of gas sensitive materials, and the preparation of organic conductor polymers. Indium nanoparticles are also widely used in catalysis, sensing, biomedicine and other fields.
