Lead-free piezoelectric 0.92(K0.445Na0.5Li0.05)NbO3-0.08BaZrO3 (KNLN-BZ) ceramics were prepared via conventional sintering. Single-step, 2-step and 3-step temperature-controlled conditions designed. The structure electrical properties of obtained using different procedures systematically studied. It was found that ceramic the method with a holding time 20 h showed highest properties. Curie temp...
