摘要：

A new system of BNT-based multi-component lead-free piezoelectric ceramics, [Bi1-z(Na1-x-y-zK Li-y](0.5)Ba-z TiO3, was prepared by conventional ceramic technique and the electrical properties of the ceramics were studied. The analysis of X-ray diffraction shows that all ceramics investigated can form a pure perovskite phase. The ceramics exhibit good piezoelectric performances and strong ferroelectricity: piezoelectric constant d(33) = 205 pC/N, electromechanical coupling factor k(p) = 37.0%, remanent polarization P-r = 38.5 mu C/CM2, coercive field E-c = 2.80 kV/mm, and high depolarization temperature T, It is obvious that [Bi1-z(Na1-x-y-zKxLiy)](0.5)BazTiO3 ceramics can be used in practical devices.
