Abstract
The precursor of ultrafine In2O3 powder was prepared by the hydrolysis, peptization and gelation of InCl3·4H2O used as raw material. After calcination, ultrafine In2O3 powder was obtained. The particles were characterized by the methods of thermo-gravimetric and differential thermal analysis (TG-DTA), X-ray diffractometry (XRD) and transmission electron microscopy (TEM), respectively.
