Properties and stability of indium oxide

Indium oxide preparation method

1. Combustion of high-purity metal indium in the air or calcining indium carbonate to produce In2O, InO, In2O3, and finely control the reduction conditions to produce high-purity In2O3. The spray combustion process can also be used to prepare indium trioxide ceramic powder with an average particle size of 20 nm.

2. When burning indium hydroxide to prepare indium trioxide, 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 resulting oxide is hygroscopic, so 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 to constant weight at 850°C to generate In2O3, and then heat it in air at 1000°C for 30 minutes. Other indium nitrate, indium carbonate, and indium sulfate can also be burnt in the air to produce indium trioxide.

The properties and stability of indium oxide

In the presence of hydrogen or other reducing agents, heating to 400-500°C can be reduced to metallic indium or low-valent indium oxide.

Decomposes into lower oxides at high temperatures. In addition, it can react with metal indium at high temperatures. Although In2O3 produced by low-temperature burning is easily soluble in acid, the more complete it is after high-temperature treatment, the more difficult it is to dissolve, and the hygroscopicity also disappears. When indium trioxide is reduced with hydrogen under red heat, metallic indium is produced.

Ecological data of indium oxide

Generally speaking, it is harmless to water. Do not discharge materials into the surrounding environment without government permission.

Overview of indium oxide powder

Indium oxide is an oxide with a molecular formula of In2O3. The pure product is white or light yellow amorphous powder, which turns into reddish brown when heated. Indium oxide is a new type of n-type transparent semiconductor functional material with wider band gap, smaller resistivity and higher catalytic activity. It has been widely used in photoelectric, gas sensor, catalyst and other fields. In addition to the above functions, when the particle size of indium oxide reaches the nanometer level, it also has the surface effect, quantum size effect, small size effect and macroscopic quantum tunneling effect of nanomaterials.

Indium oxide powder application
