Synthesis of corundum structure ITO nanocrystals by hydrothermal process at low pressure and low temperature
Source abstract
Abstract
The corundum structures of In2O3:Sn (ITO) nanoparticles were synthesized by hydrothermal processing of InCl3 and SnCl4·5H2O precursor at low temperature of 250 °C and 40 bar pressure for 3 h. The precursor was precipitated in a white gel of InOOH. After drying at 150 °C in air, it was crystallized in orthorhombic structure. InOOH powder was transformed into dark-gray rhombohedral In2O3 by sintering at 420 °C in forming gas for 1 h. The samples were characterized by means of XRD, SEM, and TEM. The particle size of the resulted ITO powder was about 32 nm.
