0.94Bi(0.5)Na(0.5)TiO(3)-0.06BaTiO(3) (BNT-06) lead-free piezoelectric ceramic has been prepared by using a novel low-temperature solid-state synthesis method. The relationship between the calcine conditions and the electrical properties of the ceramics was systematically studied. The results show that a small amount of the activated assistant additives in the raw materials by using the novel low-temperature solid-state synthesis method decreases the calcine temperature of the BNT-06 powder from 900 degrees C to 600 degrees C. The BNT-06 ceramics prepared by using this powder presents good properties with rho = 5.86 g/cm(3), d(33) = 122 pC/N, k(p) = 0.24, Q(m) = 109, T(C) = 271.2 degrees C, epsilon(r) = 1656, tan delta = 0.05, P(r) = 32.
