Effect of composition on electrical properties of lead-free Bi 0.5(Na0.80K0.20)0.5TiO 3-(Ba0.98Nd0.02)TiO3 piezoelectric ceramics

Lead-free piezoelectric ceramics with the composition of (1-x)Bi 0.5(Na0.80K0.20)0.5TiO 3-x(Ba0.98Nd0.02)TiO3 or (1-x) BNKT-xBNdT (with x = 0-0.20 mol fraction) have been synthesized by a conventional mixed-oxide method. The compositional dependence of phase structure and electrical properties of th...
