| Abstract: | The effects of high valence cations M~(n+) (n≥4) doped on the phase formation and the structure stability have been investigated. In the crystal structure X_2Sr_2Ca_2Cu_3O_(10)(X = Bi_(1-x-y)Pb_xM_y), the high valence cations M~(n+), Bi~(3+), and Pb~(2+) were deter-mined to statistically distribute at the bismuth positions. The bismuth valence is raised and the positions of oxygen atoms in the (XO_2X) double layers are fully occupied. Conseqently, The structural stability is increased. The phase 2223 was found to form more rapidly by doping and the single phase with T_c(0)>110 K can be obtained more easily. |
