relations. Another form of Cooperation is represented by the development of technical staff by means of short specialized courses in the various fields of the industrial processes.
Funding Powder processing—study of nucleation and growth processes of particles in Suspension; preparation of ZnO and Zr0 2 powders from precursors by coprecipitation and sol-gel routes; studies of densification and coalescence during sintering of oxides {ZnO, NiO). Thermomechankal ceramics—effect of sintering additives on microstructure and thermomechanical properties of SiC, Si3N4 and Si3N4/ SiC composites; influence of composition and microstructure on friction wear of sialons; equilibrium phase relationships in Si3N4-oxideSiC Systems; processing of SiC ceramics by slip casting; low temperature sintering of A1203. Electrical ceramics—effect of dopants and processing parameters on defect concentration and segregation in semiconductors; processing and properties of ZnO ceramic Varistors, resistive gas sensors (ZnO, Sn0 2 , W03), capacitors and transducers (titanates, niobates and tantalates); evaluation of mixed conductors and solid electrolytes for oxygen sensors and fuel cells and of deposition techniques for producing thin films; sintering mechanisms and phase equilibria in Y203-BaO-Cu oxide superconductors. Glasses—theoretical treatment of diffusion processes in molten glasses; volatilization in Na20-B203 glasses änd its bearing on arcmelting Operations; development of glass compositions (SiOj-ZnO, Si02-Ti02 and Si02- Al203-Li20 Systems) for chemically and mechanically resistant coating prepared by the sol-gel process. Refractories and Clay Ceramics—development of refractory compositions for glass melting pot furnace linings; study of chemical attack on alumino-silicate and basic refractories by molten salts and slags; determination of equilibrium data pertaining to corrosion processes of basic refractories; development of clay-based ceramic fabrication routes using local raw materials and industrial waste; development of ceramic enamels.
graduate and postgraduate students. With the Fbrtuguese entry into the European Common Market, a new set of opportunities has arisen, and the Department of Ceramics and Glass Engineering of the University of Aveiro has become involved in research projects with institutes and universities from England, the Netherlands, Germany, Belgium, Ireland, and France. The department is also trying to further implement the exchange of students, profiting from the European programs available with that objective.
