Document Type and Number:
Japanese Patent JP5553486
Kind Code:
B2
Abstract:
Ceramic powder comprises a pyrochlore structure (I); 0.5-10 wt.% of a secondary oxide of zirconium and/or hafnium; and optionally a sintering auxiliary agent, which is up to 0.05 wt.% of silicon oxide, up to 0.1 wt.% of calcium oxide, up to 0.1 wt.% of magnesium oxide, up to 0.1 wt.% of iron oxide, up to 0.1 wt.% of aluminum oxide and up to 0.08 wt.% of titanium oxide. Ceramic powder comprises a pyrochlore structure of formula (Gd v(Zr xHf y)O z) (I); 0.5-10 wt.% of a secondary oxide of zirconium and/or hafnium; and optionally a sintering auxiliary agent, which is up to 0.05 wt.% of silicon oxide, up to 0.1 wt.% of calcium oxide, up to 0.1 wt.% of magnesium oxide, up to 0.1 wt.% of iron oxide, up to 0.1 wt.% of aluminum oxide and up to 0.08 wt.% of titanium oxide. v : 2; x+y : 2; and z : 7. Where: y is greater than x or less than x. Independent claims are included for: (1) a ceramic layer (13) made from the powder; and (2) a layer system exhibiting a ceramic layer, which represents preferably an external layer.
