Description
The final properties of Pb- and Pr-substituted 2201 superconductors depend on processing parameters such as annealing temperature, reaction time, atmosphere and cooling schedule. As the Pr-content is reduced, their effects become more important and less reproducible. For samples having the composition Bi1.6Pb0.4Sr1.65Pr0.35CuO6+δ the Tc varies from less than 10 K up to 30 K. We have found that during the final annealing at high temperatures there is sizable loss of lead which can significantly alter the stoichiometry and properties of the superconducting phase. (orig.)
