<p>The ceramic powder has a pyrochlore phase of general formula (I), an oxide and a sintering aid. 0.5-10, particularly 5-7 wt.% of the oxide, and 92, particularly 94 wt.% of pyrochlore phase are provided. The oxide is hafnium oxide or zircon oxide. The sintering aid includes 0.05 wt.% of silicium oxide, 0.1 wt.% of calcium oxide, 0.1 wt.% of magnesium oxide, 0.1 wt.% of iron oxide, 0.1 wt.% of aluminum oxide and 0.08 wt.% of titanium oxide. The pyrochlore phase having general formula (I), A 2-B 2O 7 A : gadolinium; B : hafnium or zircon. An independent claim is also included for a coating system, which has a substrate and a metallic-binding layer, particularly yttrium-stabilized zircon oxide layer.</p> |
