Abstract
Y2O3 admired to 123 significantly influences the mechanism of melt tex turing of YBCO. Based on phase diagram considerations, it is shown tha t the process window for stable growth conditions can be considerably increased. Furthermore, a lower process temperature (T-a = 960 degrees C to 985 degrees C) becomes possible. Samples have been grown by both directional solidification and zone melting techniques. The supercond ucting properties are determined by local and integral levitation forc e measurements.
