Abstract

Ag-sheathed multifilamentary Bi-2223 tapes have been fabricated by a conventional powder-in-tube method with an optimum final heating program. Many heating programs were done by varying sintering time (t_s), post annealing time (t_p) and cooling rate (R) from sintering temperature to post annealing temperature. It is found that Jc has been increased by a factor 1.5 to 2 at 0T over the normally processed tapes, with the ΔT=(Ts-Tp)=10°C and R=0.3°C per hour conditions. XRD indicate that these tapes have a high degree of phase purity, and well-aligned grains. The typical value of Jc is 2.0-2.5×10⁴A/cm².
