| 摘要 |
A method for preparing yttrium barium copper oxide (YBCO; Y-123; YBa2Cu3O7-x) superconducting nanoparticles is disclosed. The YBCO superconducting nanoparticles are prepared via a solid-state reaction by a solid-state reaction of an yttrium precursor, a barium precursor, and a copper precursor. One or more of the precursors are metal chelate compounds having acetylacetone ligands, which are highly stable and have a high compatibility with the other precursors.
