Processing and Property Evaluation of Silver or Aluminum Matrix YBa2Cu3O6+x Superconducting Materials

Abstract

In order to understand the physical behavior at the atomistic level of the superconducting metal matrix composites, both aluminum/YBa2CU306+x and silver/YBa2CU306+x composites have been investigated. The results suggest that silver forms superconducting composites in the concentration range 10-72 wt. %. The aluminum based composites showed the superconducting property only for composites containing 60 wt.% aluminum and 40 wt. % YBa2CU306+x. In addition, it was found that the superconducting behavior of the aluminum YBa2CU306+x composites is very sensitive to the sintering temperature and the duration of sintering.
