Highly dense and phase-pure ferroelectric ceramics in the (1-x)Bi0.5K0.5TiO3–xBiFeO3 system have been prepared and examined in a wide range of composition (0.1 ≤ x ≤ 0.9). The dielectric and electromechanical properties have been shown to reach a maximum value at x ≈ 0.25 demonstrating a high strain performance (250–370 pm/V in the temperature range 25–175 °C). Stability of the strain response with respect to temperature, as well as frequency and amplitude of the driving electric field is reported and discussed.
