| 摘 要： | 用Ba(NO_3)_2代替传统BaCO_3,在较低温度下合成了零电阻温度在90K以上的超导体。用一步合成法和二步合成法分别合成了Y_2BaSrCu_3Ox超导体,研究了退火条件对体系超导性的影响,从固体化学反应角度讨论了超导相与杂相的形成,从配位化学的角度说明了Sr掺杂引起Tc值下降的原因。

| Abstract: | The superconductor above 90K is synthesized by replacing BaCO_3 with Ba(NO_3)_2 at lower temperature. The Y_2BaSrCu_3Ox Superconductors are synthesized by one step and two steps,respectivily, the formation of multiphase are discussed from the angle of solid chemical reaction. The cause of dropping Te after doping Sr ion is illustrated by ligand chemistry |
