Indium Oxide

High-purity indium metal can be burned in air or indium carbonate can be calcined to produce In2O, InO, and In2O3. By precisely controlling the reduction conditions, high-purity In2O3 can be produced. Indium trioxide ceramic powder with an average particle size of 20nm can also be produced by spray combustion process.
When preparing indium trioxide by calcination of indium hydroxide, if the temperature is too high, there is a possibility of thermal decomposition of In2O3. If the temperature is too low, it is difficult to completely dehydrate, and the resulting oxide is hygroscopic. Therefore, the heating temperature and time are important factors. In addition, since In2O3 is prone to reduction, it must be kept in an oxidizing atmosphere frequently.
Indium hydroxide was incinerated in air at 850℃ to a constant weight to form In2O3, and then heated in air at 1000℃ for 30 minutes. Other indium nitrate, indium carbonate and indium sulfate can also be incinerated in air to produce indium trioxide.
When the particle size of indium oxide reaches the nanometer level, in addition to the above functions, it also possesses the surface effect, quantum size effect, small size effect and macroscopic quantum tunneling effect of nanomaterials.
