Preparation and Characterization of Cubic and Rod-Shaped Indium Tin Oxide Powders Using the Hydrothermal Process

Article Preview

Abstract:

The cubic and rod-shaped powders of indium tin oxide were synthesized at a stable temperature reaction for 18h using the surfactant aid hydrothermal method under various conditions. The cubic and rod-shaped powder size changes with the concentration of the precursor. The finished products of indium tin oxide can be obtained by calcination at 500°C for 2h in air. Characterization was conducted using scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), X-ray diffractometry (XRD), thermogravimetric analyzer/differential thermal analysis (TG/DTA) and the Brunauer-Emmett-Teller (BET). XRD analysis shows that the conditions of this experiment can produce pure ITO powders. The characterization of cubic and rod-shaped ITO powders is also discussed.
