Dielectric and pyroelectric behavior of (PbBa)[(ZnNb)Ti]O ferroelectric ceramics.
Pyroelectric ceramics based on PZN have been obtained by standard ceramic technique. Samples of composition (PbBa)[(ZnNb)Ti] were studied, showing a pure rombohedral related-perovskite phase. Dielectric measurements exhibit a relaxor ferroelectric behavior with a transition temperature closed to roo...

Samples of composition (PbBa)[(ZnNb)Ti] 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 (R=9.7x10C/cmC) 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. Cerámicas basadas en PZN han sido obtenidas por el método cerámico tradicional a partir de la composición nominal (PbBa)[(ZnNb)Ti]. Una estructura perovskita romboédrica fue obtenida a partir del estudio estructural y el análisis dieléctrico mostró un comportamiento relajador para la transición de fase ferroeléctricaparaeléctrica con una temperatura de transición muy cercana a la temperatura ambiente. La histéresis ferroeléctrica mostró finos lazos de histéresis, característico de materiales con este tipo de comportamiento relajador. La figura de mérito piroeléctrica y la respuesta piroeléctrica dinámica mostró muy buenos resultados para aplicaciones de tipo piroeléctrica. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y custom: Copyright of Revista Cubana de Física is the property of Universidad de La Habana and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
