Beschreibung
Zusammenfassung:	A ceramic tile (1) for combustion chambers lining, in particular of gas turbines, comprises a base body (2) made of ceramic material, for example in alumina or in alumina-mullite, and a coating (3) applied to at least one face (4) of the base body (2). The coating (3) is a multilayer ceramic coating, comprising at least one outer layer (6) made of alumina or ceramic material comprising alumina, and at least one intermediate layer (5), arranged between the outer layer (6) and the base body (2) and made of ceramic material comprising mullite and preferably in mullite or in alumina-mullite.
