抄録

We have studied the quasi-binary phase diagrams of RE-Ba-Cu-O systems, in which rare earth (RE) site is composed of Nd, Sm and its mixture, along the line connecting RE123 and Ba₃Cu₅O_y (035) in 1% O₂ and 21% O₂ in Ar. The nucleation and melting of REBa₂Cu₃O_y and RE₂BaCuO₅/RE₄Ba₂Cu₂ O₁₀ were observed in situ and the liquidus lines were determined using a laser-scanning microscope. Phase identification was performed on the samples quenched from high temperatures through X-ray powder diffraction measurements and electron probe microanalysis.
