Beschreibung
Zusammenfassung:	A ceramic material having particular utility as a thermal insulating or thermal barrier coating on metallic substrates is provided. The thermal barrier coating consisting of at least 15 mol% of at least one lanthanide sesquioxide, each said lanthanide sesquioxide having a formula A 2 O 3 where A is selected from the group consisting of Pr, Nd, Eu, Tb, and mixtures thereof, and the balance comprising a first oxide selected from the group consisting of zirconia, ceria, and hafnia, said first oxide being present in an amount of at least 50 mol%. Then the present invention also broadly relates to an article having a metal substrate and a thermal barrier coating as discussed above.
