Evaluation of the degree of texturing and relative phase content in hot-pressed Bi(Pb)SrCaCuO superconductors

Abstract

Peak intensities from (001) 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 press3ng has shown strong effect on the resulting structure and physical properties with the optimum for 26MPa and 850°C between 96h and 120h. the highest value of J c for the uniaxially hot pressed pellet was ∼11,500Acm −2 at 77K and OT.
