<P>PROBLEM TO BE SOLVED: To provide an alumina porous ceramic excellent in molding strength without using e.g. an organic matter binding agent, capable of controlling the void rate after the firing in a specific range of not smaller than 5% without using a combustible pore forming agent or the like, low in its load to environment, simple in its manufacturing process, and low in its cost, and its manufacturing method. <P>SOLUTION: In this manufacturing method of an alumina porous ceramic, an alumina porous ceramic having an open pore rate of not smaller than 5% and having at least a peak of pore distribution in a range of 0.01-20μm is manufactured, and this alumina porous ceramic is manufactured by this method, and its open pore rate is controlled in a specified range not lower than 5% by the quantity of water addition, and has at least a peak pore distribution in the range of 0.01-20 μm. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
