The term "engineering ceramics" is taken here to mean the group of special high-strength, wear-, corrosion-and/or heat-resistent oxides and composite materials, which are being used for a variety of applications to support a large number of diverse industries. The basic research program on engineering ceramics comprises phase equilibria and mass-transport phenomena in systems relevant to engineering ceramics as well as microstructure- properties relationships, in particular the role of processing variables in the performance and reliability of sintered ceramic components. As part of the basic research to support ceramic technologies, emphasis will be given to interparticle forces acting between ceramic particles in aqueous and nonaqueous media, and their role in the reology of ceramic suspensions to be used in wet forming by slip casting, tape casting and injection molding. Also considered is a novel aqueous injection molding technique, the Hydrolysis Assisted Solidification (HAS) process, which relies on the time-delayed in-situ hydrolysis of AIN powder added to concentrated aqueous slurries which leads to rapid solidification of the slurry in a preheated die. The mechanisms and kinetics of the AIN hydrolysis reaction will be studied in order to control the solidification rate, which is a prerequisite for any feasibile ceramic wet-forming process. The materials investigated will be of both oxide and nonoxide classes. Emphasis will be given to alumina and zirconia toughened alumina for structural applications at low and medium temperatures, to tetragonal zirconia for dental applications, to silicon-nitride based ceramics for heat- and wear-resistant structural parts, and to SiC coated C/C composites for automotive engineering (brake-discs and pads, clutch-discs, etc.). Most of these materials and components are being produced by small and medium size domestic enterprises, which are forced to compete internationally, with the Ceramics Department at the IJS playing the role of a valuable R&D partner. In the frame of the program, the education of graduate and post-graduate students will, take place, and cooperation with foreign universities and institutes is foreseen.
