Abstract
A planetary homogenizing was employed as a novel method to prepare Al2O3 slurries. The planetary-homogenized slurries showed very low viscosity, compared to the balled-milled slurries. Moreover, the viscosity of the planetary-homogenized slurries was stable for long time. The relative density of the green bodies prepared from the planetary-homogenized slurries was about 60 % or more and was independent of the slurry solid content. Linear shrinkage of the sintered bodies prepared from the planetary-homogenized slurries was very low and independent of the slurry solid content, as compared to that of the sintered bodies prepared from ball-milled slurries.
