Description
The sequence of the different phase layers in reaction zones of the Y2BaCuO5-BaCuO2, Y2Cu2O5-BaCuO2, Y2Ba4O7-CuO diffusion couples has been established at 930-950 C in air. The Y, Ba, Cu distributions over the zones have been determined by electron microprobe analysis (EMA), and diffusion path has been plotted into isothermal section of the phase diagram. The number and the width of intermediate layers give information about the synthesis of YBa2Cu3O7-δ superconducting phases
