S7. Processing and Microstructure of Functional Ceramics: Sintering, Grain Growth and Their Impact on Materials Properties
Materials processing is important for functional ceramics applications, such as sensors, ferroelectric actuators, dielectrics, and oxygen as well as lithium-ion conductors. In these technologies, grain boundaries have a strong impact on device performance. Possible influences of processing and microstructure arise, e.g., from local defect redistribution, space charges, mechanical stresses, and anisotropy of transport processes at grain boundaries. These effects and their interplay with materials properties need to be understood on a fundamental level in order to optimize materials for given applications.
This symposium aims to bring together researchers working on all aspects of bulk functional ceramics processing, microstructure, and its evolution and relationship to materials properties. The focus is on perovskite materials (e.g. BaTiO3, BKT, KNN, SrTiO3, LLTO, BSCF), but other functional ceramics are considered (e.g. spinel, ZnO, CeO2, ZrO2, TiO2), also.
