Preparation method of high purity 115 K Tl-based superconductor |
| 摘要 |
A preparation method for high-purity Tl-based superconductor phase of 115 K, and the precursor thereof. The process comprises a specific composition of precursors, represented by the formula: (TlaPbbBic)Sr2-xCa2+xCuyOz, wherein (a+b+c)=1, 0<x</=1 and 2</=y</=4, for the manufacturing of Tl-based superconductor by adding oxalic acid as a chelating agent which equals to half the molar amount of total nitrate anions in the required metal nitrates aqueous solution and adjusting pH value of the solution to obtain the superconductor.
