Abstract

Pyroelectric ceramics based on PZN have been obtained by standard ceramic technique. Samples of composition (Pb0.8Ba0.2)[(Zn1/3Nb2/3)0.7Ti0.3]O3 were studied, showing a pure rombohedral related-perovskite phase. Dielectric measurements exhibit a relaxor ferroelectric behavior with a transition temperature closed to room temperature. Slim hysteresis loops with only small remanent polarizations were found. The figure of merit (RV=9.7x10-10C/cm2oC) and the dynamical pyroelectric response show a suitable material to be used in pyroelectric applications. The room temperature value of the dielectric permittivity shows that the studied system could be considered for potential application in the manufacture of multilayer ceramic capacitor.
