“…146 Single crystals of Bi2212 containing inclu-sions of CuO (elongated particles 1 mm in diameter and 3 ± 4 mm long) were obtained by melt ± solution crystallisation from KCl. 147 Majewski et al 148 ± 150 reported detailed phase diagram studies concerning the possibility of partial decomposition of the solid solution. If a solid solution of a particular composition is heat treated at a lower or, vice versa, a higher temperature, it loses homogeneity and submicrometre-sized inclusions of products are formed in the matrix of the starting compound.…”

Chemical aspects of the formation of microcomposites Chemical aspects of the formation of microcomposites based on superconducting cuprates are considered. The materials based on superconducting cuprates are considered. The materials are composed of a superconducting ceramic matrix and micro-or are composed of a superconducting ceramic matrix and micro-or nanoinclusions of the non-superconducting phase, which are nanoinclusions of the non-superconducting phase, which are uniformly distributed in the matrix. Requirements on the operat-uniformly distributed in the matrix. Requirements on the operating characteristics of the superconducting ceramics are described ing characteristics of the superconducting ceramics are described and routes to high critical current densites are outlined. Phase and routes to high critical current densites are outlined. Phase equilibria in the generic systems are considered. Physical and equilibria in the generic systems are considered. Physical and chemical criteria for the choice of phases that can form non-chemical criteria for the choice of phases that can form nonsuperconducting inclusions are proposed. Methods of prepara-superconducting inclusions are proposed.
