One and multi-step solid state reaction methods were used to prepare a high temperature superconductor with a nominal compositionBi2-x LixPb0.3Sr2Ca2Cu3O10+δ for ( 0 ≤ x ≤ 0 .5). T he effect o f preparation conditi...
In this work, superconducting samples of type (Bi1.8Pb0.4)Sr1.9Ca2.1Cu3O10+δ were prepared, with Pb0.4 composed of Pb0.2 2+ and Pb0.24+ , at different sintering temperatures ranging from 835℃to 855℃. The prepared s...
