摘要
The invention relates to a heat insulating layer on a metallic substrate for using for high temperatures, especially for temperatures above 1300° C. Starting with a base of La2Zr2O7, the properties of the heat insulating substance to be used as the heat insulating layer are regularly improved, by substituting lanthanum cations with ions of elements Nd, Eu, Dy, Sm and/or Gd. An additional, at least partial substitution of the zirconium cations by Ce, Hf or Ta is advantageous. Improving the properties results especially in a high thermal coefficient of dilation alpha and low heat conductivity lambda.
