Using solgel method Nd_2O_3-SiO_2 binary oxide systems were prepared. The binary oxide transformed from the amorphous phase to nanocrystalline phase upon heat treatment in air. Characterization of the Nd_2O_3-SiO_2 was carried out by using X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy. The effect of the sintering temperature and time on the evolution of the binary oxide system was discussed. It is found that sintering time plays a pivotal role to obtain Nd_2O_3-SiO_2 nanocomposite. At temperature of 900°C, the sample was sintered for 12 h and monoclinic Nd_2O_3 nanocrystallites, with average crystallite size ≈12 nm, were obtained.
