Abstract :
The influence of Rb2CO3 additive on the properties of YBCO was investigated. The impurity was added to the usual stoichiometry of Y1Ba2Cu3Oy to produce an initial batch with general formula Y1Ba2 Cu3(Rb)xOy where x=0 to 0.60. Only tracer of (2.21×10-2 wt.%) Rb were found in all samples after final baking. Adding Rb shifted the temperature Ton of the “magnetic transition” towards lower temperatures without affecting the electrical HTSC characteristics and improved the grain size homogeneity
