The cubic and rod-shaped powders of indiumtin 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 changeswiththe concentration of the precursor. The finished products of indiumtin oxide can be obtained by calcination at 500°C for 2h in air. Characterizationwas conducted usingscanning electron microscopy (SEM),energy dispersive spectrometry (EDS), X-ray diffractometry (XRD), thermogravimetric analyzer/differential thermal analysis (TG/DTA) and the Brunauer-Emm ett-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.
