Abstract

The [50(Ba0.7Ca0.3)TiO3]-50[Ba(Zr0.2Ti0.8)O3] + xmol% Y2O3 lead-free ceramics(x=0,0.2,0.4,0.6,0.8 and 1.0) were fabricated successfully by the traditional solid-state reaction. And the microstructures, phase structure, ferroelectric and piezoelectric properties were investigated for the Y2O3-modified [50(Ba0.7Ca0.3)TiO3]-50[Ba(Zr0.2Ti0.8)O3] lead-free piezoelectric ceramics. The appropriate dopant could reduce the pores in the specimens and enhance the ferroelectric properties. The optimal piezoelectric properties d*33of the lead free ceramic is 494pm/V.And the 50BCT-50BZT ceramics with 0.4mol% Y2O3possess the optimal ferroelectric properties,Pr=6.38 C/cm2.
