Abstract
The invention relates to a material for the formation of protective layers resistant to high temperatures on chromium oxide forming substrates, to a manufacturing method and to a use of these materials. It is suitable for a use as a chromium evaporation layer for metallic alloys containing chromium in the high temperature range. It is the object of the invention to provide a material for applications as a protective layer for chromium oxide forming alloys of high temperature resistance which is thermally and mechanically permanently stable and ensures a high electrical conductivity at the operating temperature of the fuel cell. In accordance with the invention, the material is formed from a spinel phase and an oxidic secondary phase which is preferably formed with an oxidic compound containing manganese.
