Abstract
For the first time large HTSC (high temperature superconductive) crystals of LuBa2Cu3O6+x (up to 5´5´0.2 mm3) were obtained from the Lu2O3-BaO-CuO system by a flux growth method. The crystals obtained were characterized by differential thermal analysis (DTA), chemical and X-ray diffraction analyses. The temperature of incongruent melting of the phase was defined more exactly (950±5oC). The composition of crystals corresponds to the formula LuBa2Cu3O6+x. The crystal structure of the tetragonal form was determined and x=0 was found for this case.
