PROBLEM TO BE SOLVED : To provide an alumina porous body having excellent characteristic in alkali resistance. SOLUTION : The alumina porous body is structured by bonding Al2O3particles to each other and the Al2O3particles are bonded with a compound (LnxAlyOz) of Al2O3and a rare earth (Ln) oxide. The rare earth (Ln) oxide is at least one kind of a rare earth oxide selected from Gd2O3, La2O3and Y2O3. COPYRIGHT : (C)2007, JPO&INPIT
