Description

Phase diagrams in BaO-R2O3-CuO systems, where R = Nd, Sm, Eu, Gd, Dy, Ho, Y, Er, Tm, Yb, Lu, are studied in the subsolidus region. For Ba2RCuO3O7-δ compound the elementary cell parameters depend on nonstoichiometry in oxygen. For Ba5-xRCu3O9.5-x compound the elementary cell parameters, interplane distances and reflex intensities are calculated assuming that the structure is tetragonal. Using methods of X-ray phase, differential thermal analyses and thermogravimetry phase formation processes both in binary and ternary systems based on hydroxides, carbonates, nitrates, acetates, formates and oxides of Ba, Cu, Y, Dy, Eu depending on time and temperature of heat treatment are studied. 3 fig.; 1 tab
