Abstract

Lead-free (Ba_0.7Ca_0.3)(Zr_0.2Ti _0.8)O₃ ceramics (BZT-50BCT) with x wt% (x=0,0.05,0.1,0.2,0.4) dopant (SiO₂ and CeO₂) were prepared by the conventional solid-state reaction from the industry available raw materials. The doping effect of SiO₂ and CeO₂ with different concentrations on the microstructures and electric properties of BZT-50BCT ceramics was systematically investigated in the present study. Moderate doping level would result in the fine microstructures and the consequent enhanced dielectric, ferroelectric and piezoelectric properties while excessive doping would cause the degradation of the properties. The best piezoelectric performance of d₃₃=476pC/N was achieved by 0.05 wt% CeO₂ doping.
