摘要
A novel method for synthesizing low-density alumina foam has been developed The alumina foam with 98 5% porosity was synthesized by an unconventional route from an aqueous aluminum nitrate-sucrose solution The resin formed by heating this solution underwent foaming and set into solid green foam, which was sintered at 1873 K The thermogram of the green foam showed mass loss in four stages The foam exhibited interconnected porous network with window size in the range 103-226 and 167-311 mu m
