Preparation of ITO Nano-Powder by the Method of Ammonia Complexation and Calcination

Article Preview

Abstract:

ITO (Indium Tin Oxides) nanopowder was prepared by ammonium-calcining method. The chemical composition, morphology and crystal structure were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Base on the nucleation and growth mechanism of the powder, the temperature of heat treatment impacting on size and morphology was discussed briefly. The results showed that the nanoITO powder of particle size 20nm-40nm with well-pleasing particle shape and dispersion can be prepared at 800°C.
