PROCESS FOR PRODUCING ALUMINUM TITANATE - BASED CERAMICS

摘要

The invention provides a process for producing a shaped body of aluminum titanate-based ceramic such as aluminum titanate or aluminum magnesium titanate having smaller shrinkage ratio relative to a shaped body of a starting material mixture, and having a smaller coefficient of thermal expansion. The invention is a process for producing an aluminum titanate-based ceramic, comprising firing a starting material mixture containing a titanium source material and an aluminum source material, wherein the BET specific surface area of the aluminum source material is 0.1 m 2 /g or more and 5 m 2 /g or less.
