Title:
ALUMINUM TITANATE CERAMIC AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2010/113869
Kind Code:
A1
Abstract:
Disclosed is a novel method for producing an aluminum titanate ceramic that shows little change in volume when heated. Specifically disclosed is a method for producing an aluminum titanate ceramic, which comprises a step in which a starting material mixture that contains a titanium source powder, an aluminum source powder and a negative thermal expansion material and/or a precursor mixture, which is converted into a negative thermal expansion material by firing, is fired. Also specifically disclosed is an aluminum titanate ceramic which is obtained by the production method. Preferable examples of the negative thermal expansion material include zirconium tungstate.
