Abstract

Air sintering and subsequent oxygen annealing at high temperatures are integral to the production of ceramic superconducting YBa2Cu3O7-δ. We present results directed toward optimizing the temperature for these two process steps, using static magnetization to determine the intragranular properties. Surprisingly, pure oxygen stabilizes the material against decomposition at temperatures near the melting point, allowing the production of significantly higher quality single phase material.
