Abstract

Compounds of the series Hg(1−x−y) BixPbyBa2CaCu2O6+δ (0≤x,y≤0.5) are synthesized directly from the metal oxides without using a precursor. Structural, and morphological investigations are made by x-ray diffraction, SEM and EDXA techniques. Bi and Pb substitution suppresses or enhances the simultaneous formation of Hg-1201 and Hg-1223 phase. Multiphase Hg0.8Bi0.2Ba2CaCu2O6+δ has a maximum Tc of 134K. For Bi and Pb concentrations higher than 0.5 mole, non-superconducting phases are formed.
