“…However, by processing in low oxygen partial pressures Ag can be used without degradation of properties. Dou et al [19] reported that Ag additions strongly react with Bi(2223) and destabilize the superconducting Table 3 The critical temperature T c,zero (K), T c,onset (K), T c (K) and mass density of the samples for System II The highest values of the offset temperature are for samples B and C. The transition width was 13 K, 10 K, 9 K, 11 K and 13 K, respectively, from sample A to E, which indicated the presence of highly pure phase structure as shown in Fig. 8.…”
