The single-phase Ba(Mg1/3 Nb2/3)O3 (BMN) powder was successfully prepared by the KCl molten salt synthesis (MSS) method. The temperature for single-phase BMN powders by MSS was about 400°C lower than that by the solid-phase method. The average particle size (APS) was about 0.91 μm at 900°C and increased with increasing synthesis temperature. Based on the APS, the activation energy for particle growth in the MSS, whose value was 64.1 kJmol-1, was attained. The sinterability of the powder prepared by MSS method was better than that prepared by solid-phase method.
