Abstract
(1 − x)(Na0.5K0.5)NbO3–x(Ba0.95Sr0.05)TiO3 [(1 − x)NKN–xBST] ceramics were synthesized by the conventional solid-state sintering, and their microstructure and piezoelectric properties were investigated. The sintering temperature of the specimens was 1075 °C in air atmosphere and a morphotropic phase boundary (MPB) was observed in the specimens with 0.03 ≤ x ≤ 0.05. Compared with the piezoelectric properties of the NKN ceramics, the enhanced d33 value of 136 pC/N and ε3 T/εo value of 671 were obtained for the (1 − x)NKN–xBST specimens with x = 0.03.
