By comparing the R-T curves and the X-ray diffraction patterns of samples containing Sb3+ and Sb5+ , we discuss the role of Sb5+ and Sb3+ in the formation of new high Tc phase. It is found that Sb3+ partly substitutes Bi3+ forming 2223 structure; but a new high Tc phase will be produced when Sb5+ is added to the system.
