Method for preparing single-domain gadolinium-barium-copper-oxide bulk superconductor with qualification inspection function
The invention relates to the technical field of high-temperature copper oxide superconducting materials, in particular to a method for preparing a single-domain gadolinium-barium-copper-oxygen superconducting block with a qualification inspection function, which comprises the following steps: preparing Gd2BaCuO5 precursor powder and liquid phase source powder; the preparation method comprises the following steps: respectively pressing Gd2BaCuO5 precursor powder, liquid phase source powder and Yb2O3 powder into a solid phase precursor block, a liquid phase block and a supporting block; respectively carrying out similarity comparison on the solid-phase precursor block, the liquid-phase block and the supporting block with the corresponding qualified models to carry out qualification inspection; the solid-phase precursor block, the liquid-phase block and the supporting block which are qualified through inspection are sequentially placed from top to bottom to obtain a whole, the whole, MgO single crystals and an Al2O3 gasket are sequentially placed from top to bottom, neodymium-barium-copper-oxygen seed crystals are placed in the center of the surface of the solid-phase precursor block of the whole, and an assembly is obtained; according to the preparation method, the assembly is infiltrated to grow a single-domain gadolinium-barium-copper-oxygen block material, and then the single-domain gadolinium-barium-copper-oxygen block material is subjected to oxygen permeation treatment to obtain the single-domain gadolinium-barium-copper-oxygen superconducting block material, so that the problem of low qualified rate in the process of preparing the single-domain copper oxide superconducting block material is solved.
