The chemical synthesis of a high-Tc Ba2YCu3O7–δ superconductor was investigated through the organometallic route, using Ba metal, Y(OPri)3, and Cu–alkoxides or Cu–acetylacetonate as starting materials. Chemically homogeneous submicron powders of single phase Ba2YCu3O7–δ were successfully prepared at...
