Abstract:
Synthesis of Sc2O3 nanopowders by direct precipitation approach has been investigated. The netlike precursor was synthesized taking ammonia as precipitant and scandium nitrate solution as mother liquor. Phase transformation of the precursor upon calcination was analyzed. The results show that Sc2O3 nanopowders calcined at 1 000 ℃ are spherical, ultrafine (40 nm), and of high purity and narrow particle size distribution.
