摘要：
Mass transfer and phase formation processes accompanying interdiffusion in the Dy2O3-BaO-CuO system are studied at 930 degrees C in air. Several phases formed by reaction diffusion are identified, and their cation stoichiometry ranges determined. Mass transfer in this system occurs primarily through diffusion of Cu and Ba cations via vacancies of single-crystal DY2O3. Structural and superconducting properties of a bulk DyBa2Cu3O7+delta single crystal are studied.
