Abstract
In this study, high purity and fine-grained Tl1212 superconductor samples were successfully synthesized from Tl0.8Bi0.2Sr2Ca0.8Y0.2Cu2O7 starting composition by a two-step solid-state reaction method using Tl-free precursor powder prepared from coprecipitation method. XRD pattern of the sample, which was sintered at 1,000 °C for 6 min essentially showed formation of high purity 1212 phase. The sample’s zero resistance critical temperature,
