Effect of silver additions on properties of (Bi,Pb)2Sr2Ca2Cu3O10 Ag high-temperature superconducting tapes

Journal Article


Abstract


  • A series of silver-sheathed (Bi,Pb)2Sr2Ca2Cu3O10 tapes with various amounts of silver were prepared and the effect of the silver additions on the superconducting properties studied. The results indicate that silver additions accelerate the formation of the high-Tc phase by lowering the sample's partial melting temperature. No effect of silver on Tc was found because the added silver is present as an isolated phase in the superconductor matrix without visible reaction or mutual diffusion between them. However, the silver additions do show a detrimental influence on Jc which decreases with increasing silver content when the tapes are treated at the same temperature. The Jc degradation is attributed to grain misalignment caused by the undesirable silver morphology. A slight improvement of Jc-magnetic field behaviour in the tapes with low silver content (x ��� 1.0) and small degradation in the samples with high silver content (x��� 2.4) is observed. �� 1994.
