Abstract
The proposed research intends to further develop in fundamental knowledge underlying ceramic powder processing and shaping of reliable, high performance engineering structures. The research activities will include investigations of the AlN hydrolysis reactions, which can either be exploited for solidification of aqueous slurries in an unpermeable mold, i.e. in aqueous injection molding, or they should be prevented during aqueous AlN powder processing. The interparticle potentials in aqueous slurries at inherent pH will be studied and manipulated in order to obtain agglomerate free, plastically deformable saturated bodies. Attempts will be made to reduce the length of surface cracks formed during diamond machining of YTZP dental ceramics, whereas sandblasting will be used to induce additional surface compressive stresses in order to compensate for the grinding induced cracks.
