Summary

With respect to biomedical applications, i. e. ceramic knee prosthesis, near-net-shape forming technologies are required and furthermore chemically derived high purity alumina powders have to be qualified. In order to achieve further improvements of the materials properties, the grain-size of the sintered parts have to be reduced further. Since pressing of extremely fine grained powders is difficult, all processes starting from a suspension are attractive in order to achieve defect-free microstructures with sub-micron grain-size.
