L. Jiang et al., IMPROVEMENT OF TRANSPORT-PROPERTIES OF B2O3-ADDED (BI,PB)(2)SR2CA2CU3OX SILVER-SHEATHED TAPES, Superconductor science and technology (Print), 11(10), 1998, pp. 1065-1067
A small amount of B2O3 was added to the (Bi, Pb)(2)Sr2Ca2Cu3Ox in silv
er-sheathed (Bi2223/Ag) tapes. Our results showed that B2O3 addition c
an accelerate the formation of the high-T-c phase (T-c approximate to
110 K), enhance flux pinning strength and decrease weak links. The tra
nsport properties of the tapes, therefore, were improved by B2O3 addit
ion.
