The structural, and dielectric and piezoelectric properties of (1-x)BaTiO3 – x Bi1/2K1/2(X1/3Nb2/3)O3 (X=Cu, X=Mg or X=Zn) ceramic were studied. The single perovskite phase was observed when x≤0.5 for X=Cu and Mg and x≤0.2 for X=Zn. As x increased, the dielectric constant peak temperature and piezoelectric properties continuously decreased for X=Mg and Zn. On the other hand, those of X=Cu possessed a local maxima at x=0.7 and the peak temperature was 200°C and the large field piezoelectric constant, d33*, was 94 pC/N.
