Effects of rare earth additive (Nd2O3) on microstructure and dielectric properties of lead zirconate titanate ceramics

摘要：

This paper presents work on studying the structure and physical properties of PZT ceramics at a morphotropic phase boundary composition (Zr:Ti=52:48) which has been modified with different quantities of neodymium oxide, Nd2O3. Phase formation and microstructure development were examined by x-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques, respectively. Dielectric properties were measured, and the relationship between properties and the amount of Nd-dopant is discussed. It has been found that in the Nd-doped samples, the highest value of dielectric constant occurred for the 0.5wt.％ sample, sintered at 1200℃, and that the maximum d31 and kp values were obtained for the 0.5wt.％ Nd composition with values of 124pCN-1 and 0.53, respectively.
