Chemical principles of the metall-oxide superconductors preparation

Chemical aspects related to the synthesis of a new family of advanced mater ials, namely, chemically and structurally complicated high-temperature supe rconducting cuprates are considered. The study of such superconductors made it possible to solve a practically important task of revealing the <<compo sition - treatment - structure - property>> correlations and greatly contri buted to the development of chemical understanding of interactions in compl icated oxide systems, high-temperature phase transformations, the nature of peritectic reactions, properties of cuprate melts and structural phase tra nsitions. Particular attention is paid to the analysis of diverse experimen tal results obtained in the studies of the physico-chemical processes occur ring in complex metal-oxide systems.
