A high temperature thermal barrier coating which consists of a stabilized ZrO2 composition for the protection of thermally loaded components (10, 10′) of a thermal machine, especially a gas turbine, is disclosed. The thermal barrier coating is stabilized with at least 15 mol % Y1+v Ta1−vO4−v, the ZrO2 is partially substituted by at least 10 mol % HfO2 and the composition is established according to the formula (Y1+vTa1−vO4−v)z(Zr1−xHfxO2)1−z, with x ranging from 0.1 to 0.5, v ranging from −0.1 to 0.2 and z ranging from 0.15 to 0.25. |
