Abstract
We have investigated powdered mixtures PbCO3 . 2PbO + Ag2O and PbCO3 . PbO + Ag2O prefired in CO2 and annealed in CO2 + O-2 atmosphere. The samples ex hibit resistive properties characteristic for superconductivity exceeding r oom temperature. (C) 2001 Elsevier Science B.V. All rights reserved.
