RESUMO

In this work some fundamental aspects on piezoelectricity and ferroelectricity of materials are commented. Several types of characterization methods are used to study a PZT-like material which is commercially produced in Brazil. Microstructure and domain patterns are revealed by chemical etching and observed by optical microscopy and electron scanning microscopy. It was possible to observe 90°and 180° domain patterns, similar to other perovskite structure ferroelectric materials...Note: The complete abstract is available with the full electronic digital thesis or dissertations
