Abstract
Behavior of Y2BaCuO5 particles in peritectic YBaCuO melts was studied. Growth kinetics of Y2BaCuO5 aggregates were followed by optical exami nation of materials quenched from different temperatures after holding for different lengths of time. In addition, the Y2BaCuO5 phase was is olated by selectively dissolving components (BaO, CuO, and Cu2O) of th e solidified material, and the morphology of its particles was investi gated by scanning electron microscopy. The results demonstrate that th e behavior of Y2BaCuO5 in peritectic YBaCuO melts depends on the chemi cal history and composition of the starting high-T-c materials.
