| 摘 要： | 本文通过比较Sb5+和Sb3+样品的R-T曲线及X射线衍射谱,讨论了Sb5+和Sb3+在新的高温相中的作用。发现Sb3+替代Bi时形成了2223结构,而Sb5+替代Bi时却形成了一种新的高温相。关键词：

| Abstract: | By comparing the R-T curves and the X-ray diffraction patterns of samples containing Sb3+ and Sb5+ , we discuss the role of Sb5+ and Sb3+ in the formation of new high Tc phase. It is found that Sb3+ partly substitutes Bi3+ forming 2223 structure; but a new high Tc phase will be produced when Sb5+ is added to the system. |
