The classical route based on powder synthesis, processing and sintering keeps up its relevant role in the mass production of advanced ceramics. This despite the increasing palette of available emerging processing methods.
R&D in this area is especially focused on innovative synthesis of high performing (e.g. nano) powders and their processing with highly reliable, predictable, cheaper and clean production cycles.
Of interest to this symposium, that follows the ones on the same subject of previous CIMTEC Conferences, are oxide and non oxide dense or porous bulk materials and particulate composites that find extensive use in an expanding range of room and high temperature civilian, industrial and defense applications.
Novel techniques and rational improvements of the conventional methods for powder synthesis; refined meso- and nano-scale characterisation of ultra fine powders coupled with an accurate control of surface chemistry and inter particle forces in colloidal processing; advances in forming techniques and green body characterisation and processing; state-of-the-art sintering theory and practice to approach a rational design of micro and nano structure for desired performance in the final products are main topics for this symposium. In all focus areas of interest to this symposium, developments in both experimental and theory and simulations will be the topics of discussion. Innovations in manufacturing allowing a more rational use of raw materials and less labour and energy may also be discussed.
