We successfully synthesized K-substituted NBT, (Na_1-yK_y)_0.5Bi_0.5TiO₃, powder samples using the polymerizable complex method. Rietveld analysis of the powder X-ray diffraction (XRD) data for the samples revealed that a morphotropic phase boundary (MPB) is located at a K content of y = 0.29 on K-substituted NBT synthesized with suppressing evaporation of bismuth and sodium.
