Method for uniformly doping nanoparticles in high-temperature superconducting material
The invention belongs to the technical field of superconducting materials, and provides a method for uniformly doping nanoparticles in a high-temperature superconducting material. According to the method provided by the invention, the nanoparticles are dispersed by using the organic gel formed by mixing the citric acid and the ethylene glycol, so that the nanoparticles are not agglomerated, and the size of the solidified and crushed organic gel condensate powder is similar to the size of the single-phase high-temperature superconductor powder, so that the organic gel condensate powder and the single-phase high-temperature superconductor powder can be uniformly mixed; and carrying out heat preservation on citric acid and ethylene glycol mixed organogel at 430-500 DEG C for several hours to completely decompose the organogel so as to prepare the nanoparticle-doped single-phase high-temperature superconductor. The method provided by the invention is simple and convenient, high in efficiency and good in controllability, and the nanoparticles can be uniformly distributed in the doped single-phase high-temperature superconductor.
