Abstract

New lead-free bismuth-containing complex perovskite solid solution, (1−x)(Bi1/2Na1/2)TiO3xBi(Mg2/3Nb1/3)O3, were synthesized by conventional solid state reaction method. Effect of Bi(Mg2/3Nb1/3)O3 on crystal structure, dielectric and piezoelectric properties were investigated. The XRD analysis showed that all compositions can form single perovskite phase with rhombohedral symmetry. Addition of small amount of Bi(Mg2/3Nb1/3)O3 improves piezoelectric properties and the optimal piezoelectric properties of d33 = 94 pC/N and kt = 0.46 were obtained at x = 0.7% and x = 0.9%, respectively. Temperature dependence of dielectric constant εr measurement indicated these compounds were typical relaxor ferroelectric.
