ABSTRACT:
In one embodiment, a solid solution material comprises, based upon 100 mole %: about 30 mol% about 95 mol % zirconium, about 0.5 mol % to about 50 mole % cerium, up to about 20 mole % of a stabilizer selected from the group consisting of yttrium, rare earths, and combinations comprising at least one of the stabilizers, and about 0.01 to about 25 mole % of a metal selected from the group consisting of indium, tin, and mixtures comprising at least one of the foregoing metals.
