Abstract
- Lead-free piezoelectric ceramics with the composition of (1-x)[Bi0.5Na0.5TiO3-0.06BaTiO3]-xBa(Ti0.90Sn0.10)O3 or (1-x)[BNT-0.06BT]-xBTS ternary system (where x = 0, 0.01, 0.02, 0.03, 0.04 and 0.05 mol fraction) have been synthesized by a conventional mixed-oxide method. The optimum sintering condition for all samples was found to be 1125 °C/2 h with a heating/cooling rate of 5 °C/min. The relative densities of all samples were ∼98% with the accompanying linear shrinkage of ∼18%. The XRD patterns of all samples showed no detected impurity phase. It was found that the composition of x = 0.03 exhibited optimum electrical properties (εr = 1895, tan δ = 0.0355 and d33 = 255 pC/N at room temperature), suggesting that this composition had potential to be a promising lead-free piezoelectric candidate compound for dielectric and piezoelectric applications.
