Near-Net-Shaping of Engineering Ceramics: Potentials and Prospects of Aqueous Injection Molding (AIMdrolysis. In the present paper the potentials and process limitations pertaining to various generic solidification types are listed, and the feasibility, performance and prospects for the industrialization of the most advanced AIM variants are discussed.

Colloidally Processed Alumina — Ceria Stabilized Zirconia Compositeszed zirconia alumina composites have lower densities, less homogeneous microstructures and broader size distribution of the alumina grains and zirconia particles than unstabilized zirconia alumina composites. (iii) The stability of tetragonal zirconia increases with increasing the ceria content.
