Abstract:
There is described a ceramic powder, ceramic layer and layer system having gadolinium/mixed crystal pyrochlore phases and oxides. Besides a good thermal insulation property, thermal insulation layer systems must also have a long lifetime of the thermal insulation layer. The layer system according to the invention has an outer ceramic layer, which comprises a mixed crystal of gadolinium zirconate and gadolinium hafnate.
