Phase stability and microstructural evolution of bismuth strontium calcium copper oxide superconducting ceramic oxides

The use of high-T;The phase stability limits were investigated when the material was at thermal equilibrium. The oxygen non-stoichiometry was measured by thermal gravimetric analysis from 300;This research was supported by U.S. Department of Energy, Office of Basic Energy Sciences, and in part by the Midwest Superconductivity Consortium under DOE Grant No. DE-FG02-90ER45427.
