Abstract

Superconducting YBa2Cu3O7-δ, ceramic pieces and fibers were prepared through a sol-gel route from ametal acetate aqueous solution of controlled pH. Concentrating the starting solution by evaporating the solvent provided a transparent viscous sol, from which gel fibers could be drawn. Further concentrating of the viscous solution led to formation of gel pieces. Conversion of gel fibers and pieces to superconductors were investigated in terms of precipitating crystalline species and electrical conductivities.
