چکیده انگلیسی
Lead-free (1−x)(Ba0.85Ca0.15)(Ti0.9Zr0.1)O3−xBiYbO3 [(1−x)BCTZ−xBYO] piezoelectric ceramics in the range of BYO concentrations were prepared by the conventional oxide-mixed method, and the effect of BYO content on their microstructure, crystalline structure, density and electrical properties was investigated. A dense microstructure with large grain was obtained for the ceramics with the addition of BYO. The ceramics with x=0.1% exhibit an optimum electrical behavior of d33~580 pC/N, r~10.9 Ω, kp~56.4%, and tan δ~1.12% when sintered at a low temperature of ~1350 °C. When the measuring electric field is 40 kV/cm, the well-saturated and square-like P–E loops for the ceramics were observed with Pr~12.2 μC/cm2 and Ec~1.83 kV/cm.
