Chemical processing and microstructure of piezoelectric lead titanate ceramics

Lead titanate-based ceramics with different microstructures were prepared from PbO-TiO\+v\2\-v\ gels with equimolar and non-equimolar mixtures of the oxides. Deviations from the initial compositions were found in the sintered materials. As a consequence, microstructures with different grain sizes an...

Description
Summary:Lead titanate-based ceramics with different microstructures were prepared from PbO-TiO\+v\2\-v\ gels with equimolar and non-equimolar mixtures of the oxides. Deviations from the initial compositions were found in the sintered materials. As a consequence, microstructures with different grain sizes and secondary phases were developed in the resultant ceramics. These microstructures had a strong influence on the piezoelectric behaviour of the materials obtained. (Original abstract)
