HTSC-ceramic and elongated melt-textured HTSC samples. The conditions of fabrication and properties of melt-textured HTSC wares have been studied. Chemical analysis, thermogravimetry, X-ray diffraction, electron microscopy. The mechanism of thermal decomposition of barium-yttrium cuprate has been determined in air and for P(O2)=750 Pa. A refined version of Y-Ba-Cu-O phase diagram has been constructed. Microstructure of melt-textured samples have been studied in detail. Significant local inhomogeneities in distribution of chemical composition and critical current and their strong mutual correlation were revealed. These data constitute important part of physico-chemical backgrounds of HTSC synthesis
