ABSTRACT

Indium hydroxide powder was prepared by precipitation method. The reaction temperature (150~250 o C) and the holding time at each reaction temperature (1~72 h) were used as experimental variables. The particle size, microstructure and crystal phase of each prepared powder were observed through X-ray diffraction (XRD), Transmission electron microscope (FE-TEM) and BET. In this study, we investigated the phase and microstructural change induced by heat treatment of indium hydroxide nanoparticles at various temperatures for different holding times.
