摘要：

Dielectric and piezoelectric properties of lead-free (1-x)(Bi0.5K0.5)TiO3-xBiFeO(3) ceramics prepared by a conventional solid-state reaction method were studied in the range of x = 0 similar to 40 mol%. A tetragonal perovskite structure was maintained at x = 0 similar to 10 mol% forming a solid solution between (Bi0.5K0.5)TiO3 and BiFeO3 with no secondary phase. Piezoelectric coefficient (d(33)) increased from 31 pC/N at x = 0 mol% to 64 pC/N at x = 6 mol% and then decreased with further addition of x. Depolarization temperature (T-d) gradually decreased with increasing x from 302 degrees C at x = 0 mol% to 163 degrees C at x = 20 mol% and slightly increased up 180 degrees C at x = 40 mol%.
