The phase structure of ceramics changes from rhombohedral to tetragonal, and the sintering temperature decreases with the increase of the ZnO content. The limited Zn<sup>2+</sup> concentration for its solubility in PZT–PMnN–PSbN systems is about 0.25% wt. At this concentration, the ceramic exhibits a density of 8.20 g/cm<sup>3</sup> and dielectric constants of 1,555 for ε<sub>r</sub> and 32,900 for ε<sub>max</sub>. The highest value of ε<sub>max</sub> (about 22,000) was found at 1 kHz at <em>T</em><sub>m</sub> around 575 K. The diffuse phase transition was determined by using the extended Curie-Weiss law. Cole-Cole analyses show the non-Debye-type relaxation in the system.</p>}, number={1D}, journal={Hue University Journal of Science: Natural Science}, author={Tho, Nguyen Truong and Vuong, Le Dai}, year={2020}, month={Jun.}, pages={5-13} }
