Superconductive body having improved properties.

摘要

Some mechanical, electrical, and thermal properties of high Tc superconductors such as (Ba, Y) cuprates can be substantially improved by the dispersal of an appropriate metal in the superconductive body. For instance, mixing Ag particles with superconductive powder of nominal composition Ba2YCu3O7 and processing the mixture in the conventional manner can produce superconductive bodies having Tc of about 93K and substantially greater fracture strength and normal state electrical and thermal conductivity than otherwise identical bodies that do not contain Ag particles.
