Abstract
Porous alumina bodies were obtained by heat treating in air porous bodies, which were produced by polymerization and drying of polymerizable W/O-type emulsions containing alumina powder. The total porosity of the alumina bodies markedly increased with the water content of W/O-type emulsions. The bending strength and compressive strength of porous alumina bodies markedly decreased with the water content of W/O-type emulsions. Both macro-pores and micro-pores existed in porous alumina bodies by the W/O-type emulsion method.
