Abstract
The Y2BaCuO5 (211) phase plays a very important role in the formation of Y-based superconducting materials. In this paper, we present the re sults of studies of 211 phase growth and morphology in peritectic liqu id formed upon melt-processing of Y-superconductors. The influence of both the chemical nature and composition of the starting precursors is analysed. Some different ways of obtaining smaller inclusions of 211 in melt are shown. The influence of ultrasonic treatment of samples up on melting is also discussed.
