ELECTROCERAMICS XI Reports Recent Advances and Emerging Trends in the Field www.electroceramics11.co.uk
Electroceramics XI, chaired by Robert Freer and Colin Leach from the University of Manchester, was held in Man chester, United Kingdom on August 31–September 4, 2008. The conference was attended by a total of 580 delegates from 41 countries, and was structured around 14 individual symposia delivering both oral and poster presentations. Following a welcome and introduction to Manchester by Simon Gaskell, a vice president of research at the University of Manchester, the opening plenary presentation was delivered by Gary Messing of the Pennsylvania State University. Messing gave an entertaining and informed appraisal of the templated grain growth method for the production of polycrystalline piezoceramics with properties approaching those of single crystals. He presented his vision for the future of the piezoceramic industry and outlined the research needed to achieve commercially viable textured piezoelectric materials. Messing said that the commercialization of textured piezoelectrics will require advances in processing and properties of these materials. The properties of current piezoelectrics are approaching those of single crystals but still lag in piezoelectric coefficient and, more importantly, coupling coefficient. If the template particles can be aligned better, then much improved texture characteristics such as higher texture fracture and narrower orientation distribution function is expected. With current tape casting technology this requires higher aspect ratio template particles that do not reduce the materials properties like the transition and Curie temperatures, Messing said. Messing also said that a much more fundamental understanding about how the domain structure is affected by the oriented grain structure is needed. This was followed by a second plenary presentation by Yukio Sakabe, of Murata Manufacturing Company Ltd., Japan, who discussed the history of barium titanate

ceramics and their future prospects. Sakabe interwove the early history of the commercialization of BaTiO3 with the formation of Murata Ltd. in the 1940s and traced the ceramic’s development through the production of fundamental electronics components, such as capacitors, thermistors, and resonators, to the present day where continuing microstructural improvements are evolving new applications, particularly in multilayer structures. Future targets include fabricating new structures on an atom-by-atom basis. In the final plenary lecture, Joachim Maier of the Max Plank Institute at Stuttgart, Germany, discussed the relevance of nano-ionic technology for mass transport and storage applications in ceramics, balanc
