摘要：

In order to understand the precise role of a NaCl-KCl flux in controlling the crystal growth process of YBa2Cu3O7-delta, the microstructure of pellets prepared with various amounts of flux were studied by means of optical microscopy. Quenching experiments indicate significant flux loss during the growth cycle and DTA reveals liquid phase formation below the peritectic decomposition. The observations suggest a complex liquid phase-promoted growth mechanism.
