Abstract (en)
[origin: WO2021198519A1] A particulate mixture having the following chemical composition, by weight percentages on the basis of the oxides: - ZrO2 + HfO2 + Y2O3 + CeO2 : the remainder to 100%; - 0% ≤AI2O3 ≤ 1.5%; - oxides other than ZrO2, HfO2, Y2O3, CeO2 and AI2O3, or "other oxides": between 0.5% and 12%; HfO2, Y2O3 and CeO2, being such that - 1.8% ≤ Y2O3 ≤ 3% and - 0.1%≤ CeO2≤ 0.9%, the particulate mixture comprising between 0.5% and 10% of an oxide pigment, as weight percentage on the basis of the particulate mixture, wherein the content of oxides which are "other oxides" and which are not included in the oxide pigment is less than 2%, as weight percentage on the basis of the oxides, more than 95% of the weight of the oxide pigment particles consisting of a material chosen from: - oxide(s) of perovskite structure, optionally totally or partially replaced with an equivalent amount of precursor(s) of these oxides, - oxides of spinel structure, optionally totally or partially replaced with an equivalent amount of precursor(s) of these oxides, - oxides of hematite structure E2O3, the element E being chosen from the group GE(1) formed by iron, chromium and mixtures of iron and chromium, - oxides of rutile structure FO2, the element F being chosen from the group GF(1) formed by mixtures of tin and vanadium, mixtures of titanium and chromium and niobium, mixtures of titanium and chromium and tungsten, mixtures of titanium and niobium and manganese, mixtures of tin and chromium, mixtures of chromium and titanium and antimony, mixtures of nickel and antimony and titanium, and mixtures thereof, - and mixtures thereof.
