Bismuth-containing superconductor.

摘要

A process for producing a sinterable doped superconductive powder which contains a sufficient amount of superconductive compound which is at least coated with sufficient uranium-235 and/or plutonium-239 dopant atoms to enable the sinterable powder to be formed into a sintered superconductive body which can be irradiated with thermal neutrons to produce from about 0.25 x 10<1><4> to about 5 x 10<1><4> fission events per cubic centimeter of the resulting irradiated superconductive body, said superconductive compound being selected from the group consisting of Bi2CaSr2Cu2O8+/-x where x ranges from zero to .5, Bi2-yPbyCa2Sr2Cu3O10+/-z where y ranges from .1 to .5 and z ranges from zero to less than 1, and mixtures thereof.
