Effects of BaSiO3 on the strain properties of Bi0.5Na0.5TiO3-based lead-free piezoelectric ceramics

Abstract

To improve the strain properties of lead-free piezoelectric ceramics, the (0.82-x)Bi_0.5Na_0.5TiO₃-0.18Bi_0.5K0.5TiO₃-xBaSiO₃ piezoelectric ceramics with x=0-5% were investigated. The piezoelectric ceramic samples were fabricated using a conventional solid-state reaction method. The results of X-ray diffraction analysis and density measurements show a single perovskite structure as a pseudo-cubic phase with a relative density of over 95%...
