Crystal structures of a high-T_c oxide superconductor Ba_0.7Y_0.3Cu₁O_x have been identified using X-ray diffractometry and electron probe microanalysis. All the major diffraction peaks can be indexed in terms of the cubic and tetragonal phases. The lattice constant a_c is 3.884 Å for the cubic phase and the lattice constants a_t and c_t are 3.856 Å and 11.64 Å, respectively for the tetragonal phase. The identified phases have been confirmed on the scanning backscattered electron images of the sample and their chemical compositions have also been determined.
