A new compound of the formula Ca2XCe2-2XSn2O7, wherein 0.35 ≦ X ≦ 0.43, with cubic pyrochlore structure was synthesized by a solid state reaction at 1450°C. Rietveld analysis based on A site substitution gave evidence that this new compound belonged to Fd3m with cubic pyrochlore structure. It was expected from chemical analysis that some of the Ce ions at the A site should be trivalent to maintain electrical neutrality of the whole crystal. This expectation is justified by the description of average ionic radii in the A site of this new pyrochlore and the model of Rietveld analysis.
