摘要：

Based on thermoanalytic investigations a melt crystallization process was developed with reduced process temperatures and process times to produce YBCO/Ag monoliths (d = 26 mm) achieving the homogenous distribution of small sized Ag inclusions. The mechanical properties are improved, but the superconducting properties at 77 It, B-0 (480 mT) and F-N (40 N) are slightly reduced compared with YBCO monoliths without an addition of Ag (750 mT and 65 N), The maximum trapped flux,vas increased to the value B-0 9.3 T at 26.5 K, instead of 8.4 T in the Ag free bulk monolith.
