Notes:
A new control method of the particle orientation structure with super high magnetic field isstudied for Al2O3 ceramics. Al2O3 slurry was made with two types of Al2O3 particles, which one wasspherical shape of, and the other one was elongated shape of. The Al2O3 ceramics of orientation structurewas fabricated by drying the Al2O3 slurry under the super high magnetic field, cold isostatic pressing (CIP)and sintering. Effects of particle shape, particle size, the solid loading, slurry viscosity, dispersant contentand the magnetic field strength on the particle orientation structure were examined in detail. Theexperimental results indicate that even the spherical Al2O3 particles can align under the magnetic field;the particle orientation degree changes with the particle shape and the solid loading under same magneticfield strength conditions, and the elongated particle system is easier to align than the spherical particlesystem; the particle orientation degree of the Al2O3 ceramics can be controlled by adjusting the particleshape, particle size, solid loading, slurry viscosity, dispersant content and magnetic field strength
