<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an aluminum titanate ceramic by firing, for a shorter time, a precursor mixture which is prepared by mixing a titania source powder, an alumina source powder and a magnesia source powder. <P>SOLUTION: The method of manufacturing the aluminum titanate ceramic is characterized in that a precursor mixture is prepared by mixing a titania source powder and an alumina source powder and dry-grinding the mixed powders with an acceleration of at least 2G in the co-presence of grinding media, and then the thus-prepared precursor mixture is fired. The titania source powder and the alumina source powder may be mixed together with a magnesia source powder or a silica source powder. The mixed powders are preferably ground by a vibration mill. An aluminum titanate ceramic powder can be manufactured by crushing the aluminum titanate ceramic which has been prepared by the above-described manufacturing method. <P>COPYRIGHT: (C)2010,JPO&INPIT |
