Method for improving preparation of precursor powder for superconducting flywheel energy storage material
The invention relates to the related field of superconducting materials, and particularly discloses a method for improving preparation of precursor powder for a superconducting flywheel energy storage material. The method comprises the following steps: S1, taking raw material powder Gd2O3, BaCO3 and CuO, weighing according to the atomic molar ratio of Gd: Ba: Cu = 2: 1: 1, respectively putting into three containers, then putting the containers into an electric heating constant-temperature drying box, setting the temperature in the drying box to be 200-260 DEG C, the drying time to be 30-45 min, and then putting the dried Gd2O3, BaCO3 and CuO into a ball mill to be subjected to ball milling and mixing to obtain Gd2BaCuO5; and S2, weighing raw material powder Gd2O3, BaCO3 and CuO according to the atomic molar ratio of Gd: Ba: Cu of 1: 2: 3, respectively filling the raw material powder into three containers, then putting the containers into the electric heating constant-temperature drying box, setting the temperature in the drying box to be 200-260 DEG C and the drying time to be 30-45 minutes, so that the current-carrying capacity and the mechanical property of the superconducting energy storage flywheel are improved, and the performance of the superconducting energy storage flywheel is improved.
