Preparation of electroceramics from metal organic precursors

This paper details the use of metal-organic compounds to prepare piezoelectric and pyroelectric ceramics. Formulations investigated include lead titanate, lead zirconate titanate and a proprietary uranium doped lead zirconate titanate, lead iron niobate pyroelectric ceramic. The principal ceramics with improved properties are described. Results of microstructural and X-ray analysis together with dielectric characterisation of the materials are presented and comparisons made with conventionally prepared material.
