In this paper we present the results of recent studies on the improvement of superconductivity in Pb x Bi 2‐ x Sr 2 CaCu 2 O y single crystals by preventing impurities incorporation, employing ZrO 2 crucible for crystal growth and post annealing the as‐grown crystals in vacuum or argon. It is realized that the superconductivity of as‐grown crystals is improved.
