Abstract:
1. A method for producing a porous sintered body of a calcium phosphate-based ceramic having a porosity of 80% or more, wherein said method comprises: (1) preparing a slurry comprising a calcium phosphate-based ceramic powder, a water-soluble high molecular compound and a nonionic surface active agent; (2) stirring said slurry vigorously to froth said slurry; (3) solidifying the frothed slurry into a gel; (4) degreasing a green block having a predetermined shape formed from said gel to remove said water-soluble high molecular compound and said nonionic surface active agent from the gel by heating at 300 to 900° C.; and (5) sintering said green block after degreasing, wherein said nonionic surface active agent is N,N-dimethyldodecylamine oxide.
