Abstract
An improved ceramic material for heat insulation with selection of specific stabilizers and adapted proportions, includes zirconium oxide with 0.2 wt. % to 8.0 wt. % of the base stabilizers: yttrium oxide (Y2O3), hafnium oxide (HfO2), cerium oxide (CeO2), calcium oxide (CaO), and/or magnesium oxide (MgO), wherein at least yttrium oxide (Y2O3) is used, and optionally at least one of the additional stabilizers: 0.2 wt. % to 20 wt. % of erbium oxide (Er2O3) and/or ytterbium oxide (Yb2O3).
