ALUMINUM TITANATE-BASED CERAMICS

摘要

The invention is to provide an aluminum titanate-based ceramics showing a good mechanical strength. The invention is an aluminum titanate-based ceramics obtained by firing a starting material mixture which contains a titanium element and an aluminum element, and further contains a chromium element and/or a tungsten element. Preferably, a content of a chromium source which contains the chromium element is from 0.001 to 5 parts by mass, and a content of a tungsten source which contains the tungsten element is from 0.001 to 1.0 part by mass relative to 100 parts by mass of the starting material mixture.
