Abstract: Microstructure of nanocrystalline Nd2O3 supported on amorphous SiO2 upon heat treatment in air at 700°C for 8-32 h has been studied by means of X-ray diffraction (XRD), Fourier transformation infrared (FTIR) and scanning electron microscopy (SEM). It has been found that the annealing time and sintering temperature played a pivotal role to obtain hexagonal and cubic neodymium oxide. The sample calcined at constant sintering temperature 700°C for 32 h was cubic Nd2O3 nanocrystallites with average size ~10 nm.
