摘要
ITO powder and a producing method of the same are provided, capable of producing ITO particles without using a solvent with a high boiling point as a solvent used in the producing step by a simple treatment method without through a heating process in an atmosphere which disadvantageously causes sintering among the ITO particles to coarsen the ITO particles. Also, an ITO powder is provided, which is suitable for a coating material for a transparent electroconductive material, the ITO powder being produced by a first step of dissolving salt containing indium and salt containing tin into an organic solvent, then adding to this organic solvent, an organic solvent containing a basic precipitant, to thereby manufacture a mixture of a precursor containing indium and tin, and the organic solvent; and a second step of applying heat treatment to the mixture of the precursor containing indium and tin, and the organic solvent in a pressurizing vessel at 200°C or more and 300°C or less, to thereby generate ITO particles.
