摘要
采用固相反应法制备了 Bi 系超导体材料,研究了制备工艺、初始原料、元素掺杂对 Bi 系超导体中高 T_c 相含量的影响.结果表明:采用高温淬冷工艺或掺入 V 或(和)Nb 可得到高 T_c 相含量高的 Bi 系超导体.
Superconducting oxides of Bi system were prepared by the method of solid state reac- tion.The effccts of preparing technology,strarting materials and doped element on the content of high T_c phase in Bi systcm superconductors were studied.The results showed that Bi system superconducting oxides with high content of high T_c phase could be ob- tained by quenching thc samplcs in air or doping V or/and Nb clcment.
