Differential thermal analysis (DTA) and thermogravimetric analysis (TGA) of Ba{sub 2}YCu{sub 3}O{sub 7-x} using conventional platinum cells yields a series of well-defined reversible thermal events between 850 and 1000{degree}C. At least one of these is interpreted as being due to the products of platinum reaction. However, changes in slope are also observe on TGA curves taken using non-reactive MgO cells. The other thermal events may therefore represent minor phase changes in Ba{sub 2}YCu{sub 3}O{sub 7-x} in response to variations in temperature/stoichiometry.
