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

Abstract 0–3 mol% BaTiO 3 doped 0.9(Na 0.52 K 0.48 )NbO 3 –0.1AgLiTaO 3 lead free piezoelectric ceramics have been prepared by employing the conventional mixed-oxide method. The doping effects of BaTiO 3 on the crystal structure, microstructure, and piezoelectric properties were investigated. The results indicate that the addition of the BaTiO 3 significantly influenced the crystal properties, microstructure, and electrical properties of NKN ceramics. The crystal structure of the 0–3 mol% BaTiO 3 doped 0.9(Na 0.52 K 0.48 )NbO 3 –0.1AgLiTaO 3 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.
