Fleischer, R L

This patent describes a process for producing a superconductive body. It comprises: providing a matrix-forming powder of oxides or precursor therefore wherein the oxide composition corresponds to the matrix composition comprised of YBa{sub 2}Cu{sub 3}O{sub 7 {minus}{ital y}} where y ranges from zero to about 1, providing an oxide additive or precursor therefore selected from the group consisting of natural uranium dioxide, uranium-235 dioxide, plutonium-239 dioxide and mixtures thereof, all of the uranium component of the additive and all of the plutonium-239 component of the additive providing dopant atoms. The natural uranium dioxide providing dopant atoms comprised of natural uranium which includes the uranium-235 isotope, forming a mixture of the matrix-forming powder and the additive or precursor therefore, heating the mixture to a reaction temperature ranging from greater than about 800{degrees} C. to below the melting point of the oxides to produce a reaction product comprised of the matrix composition and the dopant atoms.
