Abstract：The microstructure, pore structure and grain growth of porous alumina ceramics by template method are
studied by SEM. It is found that the pore structure of porous alumina ceramics by template method is uniform, interconnected
and controllable. With the increase of the solid volume fraction, the porosity of porous ceramic decreases. The wall
of hole doesn’t appeared abnormal grain growth, and the relative density of porous ceramic is much higher compare with
foaming method.
