<P>PROBLEM TO BE SOLVED: To obtain an aluminum titanate-based ceramic which has a small BET specific surface area and which exhibits a small pore volume when disintegrated into powder by effectively using fine particles of an aluminum titanate-based ceramic. <P>SOLUTION: A process for production of aluminum titanate-based ceramics comprises firing either a precursor mixture obtained by mixing fine particles of an aluminum titanate-based ceramic with a titania source, an alumina source and, if necessary, a magnesia source and/or a silica source or a powder composed of fine particles of an aluminum titanate-based ceramic itself in a powdery or formed state, preferably in a formed state. <P>COPYRIGHT: (C)2009,JPO&INPIT |
