Preparation method and application field of indium oxide In2O3

Overview of Indium Oxide In2O3 Powder

Indium oxide is an oxide with the formula In2O3. The pure product is a white or pale yellow amorphous powder, which turns reddish-brown upon heating. Indium oxide is a new n-type transparent semiconductor functional material with wide band gap, small resistivity and high catalytic activity, and has been widely used in optoelectronics, gas sensors, and catalysts. When the size of indium oxide particles reaches the nanometer level, in addition to the above functions, it also has the surface effect, quantum size effect, small size effect and macroscopic quantum tunneling effect of nanomaterials.

The preparation method of indium oxide In2O3

1. Burn high-purity metal indium in air or calcine indium carbonate to generate In2O, InO, In2O3, and finely control the reduction conditions to obtain high-purity In2O3. Indium trioxide ceramic powder with an average particle size of 20nm can also be prepared by spray combustion process.

2. When indium trioxide is prepared by firing indium hydroxide, if the temperature is too high, In2O3 may be thermally decomposed. If the temperature is too low, it is difficult to completely dehydrate, and the generated oxide is hygroscopic. Therefore, the heating temperature and time are important factors. In addition, because In2O3 is easily reduced, it must always be kept in an oxidizing atmosphere.

3. Burn indium hydroxide in air at 850°C to constant weight to generate In2O3, then heat in air at 1000°C for 30min. Indium trioxide can also be obtained by burning other indium nitrate, indium carbonate and indium sulfate in the air.

Indium Oxide In2O3 Powder Application

1. Used as spectrally pure reagents and materials for electronic components, etc.

2. It is used for protective coating of metal mirror surface, photoelectric display semiconductor film, and also used to manufacture indium salt and glass.

Raw materials often used in resistive touch screens, mainly used for fluorescent screens, glass, ceramics, chemical reagents, etc. In addition, it is widely used in traditional fields such as colored glass, ceramics, alkali-manganese batteries, and chemical reagents. In recent years, it has been widely used in high-tech fields such as the optoelectronic industry and military fields, especially suitable for processing into indium tin oxide (ITO) targets, manufacturing transparent electrodes and transparent heat reflector materials, and producing flat liquid crystal displays and defogging ice. device.
