Piezoelectric properties of lead free BaTiO3 doped 0.9(Na0.52K0.48)NbO3–0.1AgLiTaO3 ceramics

0–3 mol% BaTiO3 doped 0.9(Na0.52K0.48)NbO3–0.1AgLiTaO3 lead free piezoelectric ceramics have been prepared by employing the conventional mixed-oxide method. The doping effects of BaTiO3 on the crystal structure, microstructure, and piezoelectric properties were investigated. The results indicate that the addition of the BaTiO3 significantly influenced the crystal properties, microstructure, and electrical properties of NKN ceramics. The crystal structure of the 0–3 mol% BaTiO3 doped 0.9(Na0.52K0.48)NbO3–0.1AgLiTaO3 lead free piezoelectric ceramics were investigated with X-ray diffraction analysis. Lattice parameters were investigated to extract the relationship between the structural properties and piezoelectric properties.
