A series of solid solutions containing CO3 groups, (CyCul\_y)(Srl \_z/2Caz/2)2(Y1 \_xCax\_zSrz)Cu20 d with 0.30<x <0.70, was prepared at 1313 K under the atmosphere of 02-4202. The values ofy (0.48-0.67) and z (0.14--0.28) depend on the total Ca content, x. The length of the a-axis increases from 3.
We found a series of superconducting phases in the T1-Ba-Ca-Cu-O system and determined the crystal structures of these superconducting phases by means of the X-ray powder diffraction method. All of these superconducting phases belong to the tetragonal symmetry. They have the same lattice constant a
