[0002] In203 is a transparent semiconductor functional material. It has the unique advantages of large bandgap, low resistivity and high catalytic activity. It has application prospects in the fields of optoelectronic products, active catalysts and gas responders. For example, tin-doped oxide steel (ITO) has very high conductivity (10Q1·cm) and very high visible light transmittance (85% to 95%). Now more than 80% of the world's consumer metal steel is used to make ITO targets. ITO targets are mainly involved in the production process of liquid crystal displays (LCDs). ITO is also widely used in touch screens, organic light-emitting flat-panel displays, solar cells, photoelectric converters, infrared reflective devices, automotive heat-proof and anti-fog glass, etc. In addition, ITO films can be used in some special protection fields such as anti-radar stealth aircraft. Therefore, the preparation of high-purity oxide steel has attracted great attention from the scientific and technological community and the industrial community.
