J. Plewa et al., THERMAL INVESTIGATIONS OF REACTIVE POWDER MIXTURES AS PRECURSORS FOR MELT-PROCESSING OF YBA2CU3O7-X, Journal of thermal analysis, 48(5), 1997, pp. 1011-1026
DTA and XRD measurements were carried but with reactive precursors tak
en from the YO1.5-BaO-CuO system in order to investigate mechanisms of
YBa2Cu3O7-X formation. The reactions taking place depend strongly on
phase composition, phase purity, powder size and heating rate. Among t
he examined reactive precursors a mixture of 7Y(2)O(3)+22BaCuO(2)+10Cu
O turned out as the most suited for melt-processing.
