Abstract
A layer system is disclosed. The layer system includes a substrate and a ceramic outer layer. The ceramic outer ceramic layer is produced from a ceramic powder. The ceramic powder include a phrochlore phase according to the empirical formula AxByOz with x, y≈2, z≈7 and a secondary oxide CrOs with r, s>0.
