Synthesis and piezoelectric properties of (1 − x)(Na0.5K0.5)NbO3–x(Ba0.95Sr0.05)TiO3 ceramics
(1 − x )(Na 0.5 K 0.5 )NbO 3 – x (Ba 0.95 Sr 0.05 )TiO 3 [(1 − x )NKN– x BST] ceramics were synthesized by the conventional solid-state sintering, and their microstructure and piezoelectric properties were investigated.

BST] 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 ≤
