摘要：

The new compound Ba4CaCu3O(x) has been identified in the Ba-Ca-Cu-O system. Preliminary single-crystal X-ray diffraction data revealed that this phase crystallizes in an ordered cell based on a cubic perovskite framework, but with doubled unit cell constants. The compound, which is not superconducting, is isomorphic with the known Ba4YCu3O(x). Equilibrium relationships to and near Ba4CaCu3O(x) in the Ba-Ca-Cu-O phase diagram are reported.
