Summary

THE AUTHORS STUDIED THE EFFECT OF BISMUTH/LEAD RATIO AND ANNEALING TEMPERATURE ON CRITICAL TEMPERATURE AND FORMATION OF THE HIGH-CRITICAL TEMPERATURE PHASE IN THIS SUPERCONDUCTOR BY THE THREE-STEP REACTION PROCESS. THE OPTIMUM BISMUTH/LEAD RATIO IS ABOUT 1.8:0.3 AND THE OPTIMUM ANNEALING TEMPERATURE IS ABOUT 1108-1118 K (845-855 DEG C). THE ZERO-RESISTANCE TEMPERATURE OF THE HIGH-CRITICAL TEMPERATUREPHASE DECREASED WHEN THE ANNEALING TEMPERATURE INCREASED, ALTHOUGH THE PHASE IS ISOSTRUCTURAL WITH THE 110 K PHASE.
