Spray combustion synthesis of nanocrystalline Y2O3 and its thermodynamical and morphological study

Nano Y2O3 particles with a spherical shape and narrow size distribution have been prepared by a novel spray combustion method. The experimental procedure is briefly described and the thermodynamical process of the post-heat treatment is investigated in this paper. The precursor fully crystallized when treated at as low as 400 °C. Prepared particles showed spherical shape and well dispersibility under different treating conditions. Narrow size distribution of particles was achieved even when the precursor was treated at 1373 K.
