摘　　要：本工作研究了YBa_2Cu_3O_(7-y)超导陶瓷的制备工艺,通过Sb^(5+)掺杂,改善了工艺条件,扩展了烧结温区,制备了T_c为80K的YBa_2Cu_(1-x)Sb_xO_(7-y)(0≤x≤0.15)超导陶瓷材料,并从理论上分析讨论了Sb^(5+)的作用机理。Manufacturing process of YBa2 Cu3O7-y, system ceramice has been investigated and improved in our work. The sintering temperature region is broadened by Sb5+ doping. Superconductive ceramics of YBa2Cu1-x SbxO7-y, (0≤x≤0.15) with Te 80K is prepared and the effect mechanism of Sb5+ doping is also discussed.
