Improved Fabrication of YBa2Cu3O7 —x Superconductors

An improved method of manufacturing high-temperature superconductors of general composition YBa2Cu3O7— x and various grain structures has been devised. This method involves mixing, pressing, and heating of Y2O3, CuO, and Ba(NO3)2 powders. This method is easier than an older method that involved mixing and sintering of Y2O3, CuO, and BaCO3 powders followed by repeated grinding and sintering, followed by pressing to final size and shape.
