The method for developing the YBa 2Cu 3O 9- x system of ceramics material with high temperature superconduction is presented in this paper, and the effect of all factors on its electric characteristics is also studied. By analyzing X ray diffraction and observing electrical scanning mirror, this sample is proved to be Ca Ti ore structure. A kind of ceramics material with high temperature superconduction is gotten. Its zero resistance is 98?K and diamagnetism is good. The technological conditions for calcining TlBaCaCu 2O y new system is researched. The ceramic material with high temperature superconduction of T1 series with zero resistance of 116.5?K is gotten and it has good diamagnetism.
