摘要
Porous alumina sintered bodies were fabricated by a new gelate-freezing method. The fabricated porous alumina sintered bodies possess highly continuous open pores, and a wide range of pore size (20-200 mu m) and porosity (30-70%). Inside the alumina only a few micro voids were observed. Pore size and porosity were able to be controlled by the alumina and water content in the slurry, and by the cooling temperature and direction.
