Abstract
The effect of silver additions, to bulk Tl0.5Pb0.5Sr2CaCu2O7-delta-Ag- x (x=0.0, 0.008, 0.016, 0.1, 0.37, and 1.0) superconductor, on microst ructure and electrical properties were studied. A Eutectic-like reacti on between (Tl-1212 + Ag) was observed. In the case of x = 0.37, liqui d phase was formed at 830 degrees C resulting in enhanced densificatio n and grain growth. Changes in T-c with silver content were observed, but the presence of silver does not cause any change in the intragranu lar J(c) values, which was on the order of 10(6) A/cm(2) at 40K in sel f field.
