Abstract

Unmanned space experiments were performed with the aim of growing large grain Gd-Ba-Cu-O superconductors in space. The advantage of the space experiment was the support of a large precursor block by a small seed crystal alone. Three samples were safely returned from space. It was interesting to note that one of the samples was mainly composed of Gd₂BaO₄ pillar shaped crystals. Detailed characterization of this new phase showed that the phase is very stable under severe conditions and will be a firm framework for the melt growth process. Infiltration of Ba-Cu-O phase into a precursor Gd ₂BaO₄ block enabled us to grow a large grain bulk Gd-Ba-Cu-O 14 cm in diameter.
