PROCESS FOR PRODUCTION OF ALUMINUM TITANATE-BASED CERAMICS

摘要

The invention is for obtaining aluminium titanate-based ceramics having a small BET specific surface area and having, when ground into powder, a small pore volume, by effective utilization of particulate aluminium titanate-based ceramics. A pre-mixture prepared by mixing a particulate aluminium titanate-based ceramics with a titania source and an alumina source and optionally further with a magnesia source and a silica source, or particulates of aluminium titanate-based ceramics is, as such or preferably after shaped, fired as the powder or as the molded body to produce an aluminium titanate-based ceramics.
