Description

This paper reports on the influence of the ionic size of the lanthanides R on melting relations of Ba2RCu3O6+x, where R = Y, Eu and Nd, studied and compared with that of a high-Tc superconductor mixed-lanthanide phase Ba2(Y.75Eu.125Nd.125)Cu3O6+x. These materials have been characterized by a variety of methods including differential thermogravimetric analysis (DTA), scanning electron microscopy (SEM) with energy dispersive x-ray spectroscopy (EDX) and x-ray powder diffraction. Single phase samples of Ba2(Y.75Eu.125Nd.125)Cu3O6+x were annealed at 1004, 1040, 1052, 1060, 1078, 1107 and 1160 degrees C and quenched into a helium gas container cooled by liquid nitrogen
