| 中文摘要 | (1？x)K0.02Na0.98NbO3–xBaTiO3 ceramics were prepared by the solid state reaction method, and their electrical properties were investigated. The samples showed crystal structure changing from monoclinic to orthorhombic, and then to tetragonal, with an increase in BaTiO3 content. The addition of BaTiO3 markedly enhanced ferroelectric and piezoelectric properties of K0.02Na0.98NbO3 ceramics. Remnant polarization increased and coercive field decreased only in the samples with small amount of BaTiO3. Piezoelectric properties were improved with the addition of BaTiO3. The 0.9K0.02Na0.98NbO3–0.1BaTiO3 ceramics showed maximum piezoelectric constant (d33 = 160 pC/N), which was even comparable with that of (1？x)K0.5Na0.5NbO3–xBaTiO3 ceramics. Their good piezoelectric properties, along with a low ferroelectric–ferroelectric transition temperature (TF–F), made the 0.9K0.02Na0.98NbO3–0.1BaTiO3 ceramics a potential candidate for lead-free piezoelectric applications. |
