Abstract

Degradation of melt‐processed Y1Ba2Cu3O7−x has been observed when the superconducting material is subjected to prolonged contact with moisture. This degradation manifests itself in a reduction in the critical current level. Results indicate that connections between grains degrade faster than the intragranular material itself. After prolonged exposure the material will eventually break apart into individual grains which are still superconducting.
