Equilibrium tie-line in PrO_y-BaO-CuO ternary phase diagram around peritectic temperature of Pr_1+xBa_2-xCu_3O_7-δ

摘要

This paper presents tie-lines between Pr_1+xBa_2-xCu_3O_7-δ and liquid on a PrO_y-BaO-CuO ternary phase diagram at 965, 970, 975, 980, and 990 deg. C in air Atmosphere, for which knowledge is necessary to fabricate composition controlled Pr_1+xBa_2-xCu_3O_7-δ single crystals by the solution growth method. Liquidus faces have Been investigated y dipping MgO single crystal rods into the thermal equilibrium Melt at various temperatures and analyzing the composition of he adhering melt by ICP.
