Abstract

Abstract Bi 1.84Pb 0.34Ca 2Sr 2Cu 4O y superconducting tapes with zero resistance at 100 K have been fabricated via the glass-to-ceramic route. After heat treatment at 842°C for > 48 h in an atmosphere of Ar+O 2,Bi 1.84Pb 0.34Ca 2Sr 4Cu 4O y tapes consist mainly of a phase with a critical temperature of 110 K. The critical current density, J c, is 6 A/cm 2 ay 77 K in zero magnetic field. The possible formation mechanism of the phase with a critical temperature of 110 K from a glass is discussed. The experimental results suggest that liquid phase formation assists the dissolution of the phase with a critical temperature of 75 K phase and the formation of the phase with a critical temperature of 110 K.
