CERAMIC BODY COMPOSED OF AN ALUMINIUM TITANATE MIXTURE

摘要

A ceramic body based on an aluminum titanate system has the following composition: i) approximately >95% by weight Al2O3.TiO2; ii) approximately 0.1-approximately 5.0% by weight SiO2; iii) approximately 0.1-approximately 5.0% by weight MgO; iv) approximately 0-approximately 2.0% by weight Fe2O3; v) approximately 0-approximately 1.0% by weight BeO, BaO or CaO; vi) approximately 0-approximately 1.0% by weight Li2O, Na2O or K2O; vii) approximately 0-approximately 2% by weight impurities. The ceramic body has a mass ratio TiO2:Al2O3 that is in a range between approximately 0.75 and approximately 0.95.
