Abstract
The preparation of high Tc superconducting YBa2Cu3O7−δ compound was investigated through organometallic route, using Ba metal, Y(O–iPr)3 and Cu-alkoxides or Cu-acetylacetonate as starting materials. Chemically homogeneous submicron powder of orthorhombic YBa2Cu3O7−δ was prepared as a single phase by controlled partial hydrolysis of metal alkoxides. It was confirmed by dc resistivity and magnetic susceptibility measurements that single phase YBa2Cu3O7−δ ceramics exhibited superconductivity at about 90 K (Tc onset).Keywords
