摘要：
The samples of (R-E,M)(2)Ca0.5Sr0.5Cu2O6+delta are prepared by solid state reaction method. The single phase boundary of R-E and M in (R-E,M)(2)Ca0.5Sr0.5Cu2O6+delta is 1.0 similar to 2.0 and 0 similar to 1.0 respectively. In (Pr,M)(2)Ca0.5Sr0.5Cu2O6+delta, the phase boundary of Sr is 0 similar to 1.0. The structure of (R-E,M),Ca0.5Sr0.5Cu2O6+delta belongs to the structure type of 212 cuprate superconductors with space group 14/mmm.
