Method for preparing Bi-2212 superconducting material
The invention discloses a method for preparing a Bi-2212 superconducting material, which comprises the following steps: directly mixing Bi2O3, a 14: 24 AEC phase and a 9: 16 CF phase and then carrying out heat treatment reaction to generate Bi-2212, or directly mixing the Bi2O3, the 14: 24 AEC phase and a 2: 4 CF phase and then carrying out heat treatment reaction to generate Bi-2212, or directly mixing the Bi2O3 and a 3: 2 AEC phase and then carrying out heat treatment reaction to generate Bi-2212. The method is inspired by a Bi-2212 semi-melting heat treatment process, the Bi-2212 superconducting material with high superconducting phase purity is obtained by mixing three or two reactants, the improvement of the current-carrying performance of the Bi-2212 superconducting wire is facilitated, the preparation process is simple, the cost is low, the controllability and operability are high, and the engineering application of the Bi-2212 superconducting material in a high-field magnet is facilitated.
