Aligned alumina was synthesized by using colloidal processing and a high magnetic field. Fine alumina powder dispersed in suspension was oriented under a high magnetic field (10 T) owing to crystal magnetic anisotropy. When the green compact prepared by slip casting in a high magnetic field was annealed at low temperatures, grain growth occurred with grain alignment. During annealing at high temperatures platelet grains grew, thus the degree of alignment increased. The c-plane of alumina was perpendicular to an applied magnetic field.
