Аннотация:This survey deals with the thermodynamic and structural problems of chemistry of high-T-c Nd-Ba-Cu-O superconductors. We show that the investigations of this model system can contribute greatly to the development of chemical knowledge of interactions of other complex metal oxide systems, high-temperature phase transformations, the nature of peritectic reactions, properties of cuprate melts, structural phase transitions, and synergism of the oxygen and cation nonstoichiometry of solid phases. Special attention is paid to the classification of extant experimental data based on a methodological analysis of physicochemical tendencies in the processes involved.
