摘要：
Peak intensities from (00l) planes of the 2223 phase was measured to receive information on the c-axis orientation, while the ratio of (0 0 10) and (0 0 14) peaks intensities of the high-T-c 2223 phase to the (0 0 8) and (0 0 12) peaks of the low-T-c phase gave information on the relative content of the high-T-c phase. Sintering prior to hot pressing has shown strong effect on the resulting structure and physical properties with the optimum for 26MPa and 850 degrees C between 96h and 120h. The highest value of J(c) for the uniaxially hot pressed pellet was similar to 11,500 A cm(-2) at 77K and 0T.
