Abstract

The textured porous Al₂O₃ ceramics were prepared by slip casting in a strong magnetic field of 6 T and subsequently sintering. The c axis of Al₂O₃ grain was oriented parallel to the direction of the magnetic field and the textured porous microstructure with plate-shape grains was formed. The porosity of textured porous Al₂O₃ ceramic was 30.37% and the relative density reached 66.29% when the sintering temperature is 1600°C. The textured porous Al₂O₃ green body showed the linear shrinkage anisotropy. The bending strength of the textured porous Al₂O₃ ceramics depended on the alignment direction of plate-shape grains. The textured porous Al₂O₃ ceramics can be prepared by slip casting in a strong magnetic field of 6 T and subsequently sintering.The textured porous microstructure with plate-shape grains is obtained. The textured porous Al₂O₃ green body shows the sintering shrinkage anisotropy. The textured porous Al₂O₃ ceramic has the anisotropic bending strength based on the orientation of grains.
