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