Molten salt synthesis of NdAlO3 powders

NdAlO3 powder was synthesized by reacting equimolar amounts of Nd2O3 and Al2O3 powders in NaCl or KCl salt. The synthesis temperature for NdAlO3, using NaCl or KCl salt was 1100 degrees C which is 500 degrees C lower than that in the conventional mixed- oxide method. The synthesized NdAlO3 powders retained the morphology of the original Al2O3 particles, indicating that a template formation mechanism plays an important role in the molten salt synthesis of NdAlO3.
