Improvement of the phase formation and superconductivity of the (Bi,Pb)2Sr2Ca2Cu3Ox silver sheathed tapes with B2O3 addition
Improvement of the phase formation and superconductivity of the (Bi,Pb)2Sr2Ca2Cu3Ox silver sheathed tapes with B2O3 addition
In (Bi,Pb)2Sr2Ca2Cu3Ox silver-sheathed (Bi2223/Ag) tapes, melted liquid phase plays an important role to form the Bi2223 phase. We have added a small amount of B2O3 into Bi2223/Ag tapes to assist in inducing melted phase because B2O3 has a melting point (460°C) much lower than the general sintering temperature of the tapes, and studied the influence of B2O3 doping on the microstructure and critical current density (Jc) of Bi2223/Ag tapes. The results show that B2O3 doping is really effective to result in the faster growth and better alignment of the Bi2223 grains in the superconducting core and improve the magnetic field dependence of the Jc value.

Abstract
In (Bi,Pb)2Sr2Ca2Cu3Ox silver-sheathed (Bi2223/Ag) tapes, melted liquid phase plays an important role to form the Bi2223 phase. We have added a small amount of B2O3 into Bi2223/Ag tapes to assist in inducing melted phase because B2O3 has a melting point (460°C) much lower than the general sintering temperature of the tapes, and studied the influence of B2O3 doping on the microstructure and critical current density (Jc) of Bi2223/Ag tapes. The results show that B2O3 doping is really effective to result in the faster growth and better alignment of the Bi2223 grains in the superconducting core and improve the magnetic field dependence of the Jc value.
