The invention relates to a material, in particular for a thermal insulation layer, with increased thermal stability, a low heat conductivity and a large thermal coefficient of expansion. According to the invention, said material comprises lanthanides, in particular the elements La, Ce, Nd, Yb, Lu, Er or Tm, which preferably occur as a mixture in a Perovskite structure. Said thermal insulation layer is particularly suitable for replacing thermal insulation layers comprising yttrium stabilized zirconium oxides (YSZ) as the thermal stability thereof is given as well over 1200&deg; C.

Material for thermally loaded substrates

In a dispersoid-reinforced electrode with a net-like open pore structure and a ceramic and a metallic meshwork, ceramic particles with an average particle diameter of less than 100 nm are homogeneously distributed in the metallic network thereby reinforcing the electrode.
