Description	Journal: Japanese Journal of Applied Physics High-density perovskite titanate zirconate-modified potassium niobate solid solutions $0.92(Na_{0.5}K_{0.5})NbO_{3}–xBaZrO_{3}–(0.08-x)(Bi_{0.5}K_{0.5})TiO_{3}$ (BBK) and Mn-added BBK have been prepared by the solid-state reaction method. The phase diagram summarized from the dielectric measurement reveals that there exists a tetragonal–rhombohedral morphotropic phase boundary (MPB) for both solid solutions. The piezoelectric properties show enhanced behavior at around the tetragonal–rhombohedral MPB. Mn addition could increase $Q_{m}$ as well as $k_{p}$ and $d_{33}$. The behavior is attributed to oxygen vacancy formation and grain size growth, respectively.
