<p>An alumina porous body which comprises coarse alumina particles (1) as a filler and SiO2, said alumina and SiO2 forming an Al2O3-SiO2 compound (mullite (2) on the surface of the coarse alumina particles through the reaction between them that takes place at the time of firing, said compound binding said coarse alumina particles, forming pores between them. A process for producing an alumina porous body which comprises mixing coarse alumina particles with SiO2, molding the mixture, and firing the molding at a temperature below 1700 DEG C, thereby sintering the coarse alumina particles.</p> |
