Pyrochlore/defective fluorite zirconate
A composition comprising a rare earth doped zirconium/hafnium oxide having a defective fluorite or pyrochlore structure is provided. The rare earth doped zirconium/hafnium oxide has the formula: (Ln1aLn2aLn3aLn4aLn5b) 2M2O7, where each of Ln1, Ln2, Ln3, Ln4 and Ln5 is a different rare earth element such that Ln1 and M have a first atomic radius ratio of 1.35 to 1.45, Ln2 and M have a second atomic radius ratio of 1.35 to 1.45, Ln3 and M have a third atomic radius ratio of 1.46 to 1.78, Ln4 and M have a fourth atomic radius ratio of 1.46 to 1.78, a is 0.2 or 0.25; b is 0.2 when a is 0.2, and b is 0 when a is 0.25; and M is Zr, Hf or a mixture thereof. A method of forming a coating comprising the composition and the resulting coated part are also provided.
