In this work, the molten salt synthesis technique was applied to the synthesis of DyAlO3 powder using NaCl or KCl salt as theflux. DyAlO3 powder was synthesized by reacting equimolar amounts of Dy2O3 and Al2O3 powders in NaCl or KCl salt. Thesynthesis temperature for DyAlO3 using NaCl or KCl salt was 1300 oC which is about 400 oC lower than that in theconventional mixed-oxide method. The synthesized powders have been characterized using powder X-ray diffraction (XRD)analysis and field emission scanning electron microscopy (FE-SEM). The synthesized DyAlO3 powders retained themorphology of the original Al2O3 particles, indicating that a template formation mechanism plays an important role in themolten salt synthesis of DyAlO3.
