Diffuse Phase

The effect of the ZnO addition in pure perovskite PZT-PMnN-PSbN ceramics sintered from 950 to 1200oC has been investigated. The phase structure of ceramics changes from rhombohedral to tetragonal and the temperature decreases with the increase of the ZnO content. The limitation of Zn2+ concentration for the solubility in PZT–PMnN–PSbN systems is about 0.25% wt., at which the ceramic shows some good physical properties such as the density of 8.20 g/cm3, some dielectric constants including εr = 1,555 and εmax = 32,900. The highest value of εmax about 22,000 was found at 1 kHz at the temperature of Tm around 575 K. Using an extended Curie-Weiss law the diffuse phase transition was determined. Cole-Cole analyses showed the non-Debye type relaxation in the system
