Defect engineering of BCZT-based piezoelectric ceramics with high piezoelectric properties
文献摘要:
The intrinsic conduction mechanism and optimal sintering atmosphere of(Ba0.85Ca0.15)(Zr0.1Ti0.9)O3(BCZT)ceramics were regulated by Mn-doping element in this work.By Hall and impedance analysis,the undoped BCZT ceramics exhibit a typical n-type conduction mechanism,and the electron concentration decreases with the increasing oxygen partial pressure.Therefore,the undoped ceramics exhibit best electrical properties(piezoelectrical constant d33=585 pC·N 1,electro-mechanical coupling factor kp=56%)in O2.A handful of Mn-doping element would transfer the conduction mechanism from n-type into p-type.And the hole concentration reduces with the decreasing oxygen partial pressure for Mn-doped BCZT ceramics.Therefore,the Mn-doped ceramics sintered in N2 have the highest insulation resistance and best piezoelectric properties(d33=505 pC·N-1,kp=50%).The experimental results demonstrate that the Mn-doping element can effectively adjust the intrinsic conduction mechanism and then predict the optimal atmosphere.
