| 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. |
