Al2O3/SiC whisker and Al2O3/ZrO2/SiC whisker compacts with high green density (66–69%) and homogeneous microstructure were prepared by suspension processing. Procedures for optimizing particle/whisker codispersion and subsequent consolidation by slip casting are described. Although densification is severely inhibited by Sic whiskers, compacts prepared by suspension processing show significantly higher sintered densities compared to dry-pressed samples. Suspension-processed samples containing 15 vol% whiskers could be pressureless sintered to relative densities in the range 93–99%.
