The invention discloses a high sintering activity nanometer indium oxide powder and a preparation method thereof. In the present invention, nano tin hydroxide (Sn(OH) 4 ) particles are introduced as a nucleation inducer for indium hydroxide (In(OH) 3 ) particles, added to the indium-containing aqueous solution, and then added with ammonia to react to generate In ( OH) 3 precipitate, through high temperature and low pressure aging, washing, drying and multiple calcinations, to obtain nanometer indium oxide powder with good dispersibility, narrow particle size distribution and high sintering activity. The nanometer indium oxide powder prepared by the invention is suitable for sintering high-density indium tin oxide (ITO)-based targets from green bodies formed by cold isostatic pressing. |
