Abstract The hydrated basic carbonate-sulfate precursor was synthesized using scandium sulfate as mother liquor and urea as a precipitating agent by a microwave heating approach. The phase transformation processes of the precipitate precursor were analyzed by DSC/TG, FTIR and XRD. Two synthesis methods of Sc2O3 powder were compared. The results showed that highly pure, ultrafine, well dispersed, narrow particle size distribution and spherical Sc2O3 nanopowders can be obtained by calcination at 1000oC for 3 h in resistance furnace or irradiation at 900oC for 20 min in microwave furnace.
