Abstract
A superconducting material includes YBa2Cu3O7-δ and a nano-structured, preferably nanowires, WO3 dopant in a range of from 0.01 to 3.0 wt. %, preferably 0.075 to 0.2 wt. %, based on total material weight. Methods of making the superconductor may preferably avoid solvents and pursue solid-state synthesis employing Y, Ba, and/or Cu oxides and/or carbonates.
Claims12
A superconducting material, comprising:
- a YBa2Cu3O7-δ matrix phase;
- and
- 0.05 to 0.2 wt. %, based on total superconducting material weight, of particles of a dopant, wherein the dopant is a nano-structured WO3 in the form of WO3 nanowires and wherein the WO3 nanowires are disposed within voids between grain boundaries of the YBa2Cu3O7-δ matrix phase.
