摘要：
The phase evolution, critical current density (J(c)) and irreversibility field (H-irr) for (Bi,Pb)(2)Sr2Ca2Cu3O10 (2223) tapes have been studied through a two-step sintering process. The tapes sintered at 840 degrees C without second-step annealing at 820 degrees C contain a small fraction of (Bi,Pb)(2)Sr2CuO6 (2201). 2201 phase vanishes when the tapes are annealed at 820 degrees C for 30 h after sintering at 840 degrees C. (Bi,Pb)(2)Sr2CuO6 (2201) phase was found to be the predominant factor for the depression of J(c) of the tapes. The J(c) vs. magnetic field shows that the depression of J(c) occurs only in the low field region, indicating that 2201 phase act as weak links in the tapes. (C) 1997 Elsevier Science B.V.
