|Title:||Effect of sintering time on particle size of rare earth compounds (R = Nd) prepared by wet chemical method|
Scanning electron microscopy
|Abstract:||Microstructure of nanocrystalline Nd<sub>2</sub>O<sub>3</sub> supported on amorphous SiO<sub>2</sub> 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 Nd<sub>2</sub>O<sub>3</sub> nanocrystallites with average size ~10 nm.|
