Effect of oxide additions on the properties of plasma-sprayed Y-Ba-Cu-O coatings
Plasma-spraying is a potential technique for forming flexible tapes from the brittle highTc oxides. It is possible to obtain superconducting YBa2Cu3Ox coatings by a suitable heat-treatment after spraying. In an effort to improve the critical current densities of the coatings, the effect of additions of Ag2O, Bi2O3 and SnO2 to the YBa2Cu3Ox powder used for spraying was studied. The maximumJc value of 75 A/cm2 was obtained for the sample doped with 5% SnO2.
