摘要
本文通过比较Sb^(5+)和Sb^(3+)样品的R-T曲线及X射线衍射谱,讨论了Sb^(5+)和Sb^(3+)在新的高温相中的作用。发现Sb^(3+)替代Bi时形成了2223结构,而Sb^(5+)替代Bi时却形成了一种新的高温相。
By comparing the R-T curves and the X-ray diffraction patterns of samples containing Sb3+ and Sb5 + , we discuss the role of Sb3+ and Sb3+ in the formation of new high 7% 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.
