In this study, using spherical alumina powder with a narrow particle size distribution as the coarse powder, slips were prepared from a bimodal size distribution alumina powder mixture, of which the particle size ratio of the coarse to the fine powder was about nine and the mixing ratio of the coarse and fine powders was 7:3, and cast. A green compact which had a high packing density of about 78% and a uniform packing structure was obtained when slips in which the particles were sufficiently dispersed and the alumina content was about 49vol%, were cast.
