Abstract

The stability of double-side-coated Bi2Sr2CaCu2O8 (Bi-2212) tapes on Ag substrates in a water environment has been studied. A phase analysis of the as-processed tape conductors was performed and indicated that aqueous precipitates are formed in the tapes exposed to aerated water solution. The nominal composition of the precipitates was found to be Sr1-xCaxCuO2 (x≈0.4). This phase is present in the tapes before the corrosive damage ensues. In order to evaluate the stability properties of the Sr0.6Ca0.4CuO2 phase in a water environment, the pure compound was synthesized and treated under the same conditions as the tapes. Studies reveal that similar corrosion occurs in the Sr0.6Ca0.4CuO2 phase. Thus, the presence of this impurity phase, which appears upon heat treatment of the tape assemblies, is found to be an important factor in the degradation behaviour of the Bi-2212 tape conductors.
