摘要

Using CaCl_2 as sintering aid, the Tb-doped (Ba_(0.859) Ca_(0.141)) (Zr_(0.106) Ti_(0.894)) O_3 (BCZT) ceramics were fabricated by conventional solid-state reaction method. The sintering temperature of ceramics decreases from about 1450°C down to about 1300°C. The SEM micrographs show that all ceramics sintered above 1300°C are very dense and have clear grain boundaries. A piezoelectric coefficient of d_(33) 659 pm/V was obtained at 0.3 mol.% Tb-doped (Ba_(0.859) Ca_(0.141)) (Zr_(0.106) Ti_(0.894)) O_3 with CaCl_2 sintered at 1350°C and residual polarization of that can reach 11.70 μC/cm~2. The results indicated that the excellent piezoelectric property could be a promising candidate for electronic industry purposes.
