摘要：
The formation of (R,B)-1212 phase and Superconductivity in Cu0.5B0.5SrBaR0.6Ca0.4Cu2Otau system were investigated (R = rare earth elements). It is found that in this system, (R,B)-1212 phase can be formed For R=La, Pr, Nd, Sm, Eu, Gd, Y, Dy, Ho, Er, Tm and Yb except for R=Ce and Tb. T-r of the (R,B)-1212 phase increases with the decrease of R atomic radius for La (29 K), Nd (43 K), Sm(49 K) En (54 K), Gd(66 K) and Dy(74 K), and keeps nearly a constant value of 75 K for R=Y, Ho, Er, Tm and Yb. (R,B)-1212 phase for R=Pr can be formed also, but it is not superconducting.
