  • Method for preparing yttrium barium copper oxide (YBCO) superconducting nanoparticles
    Patent number: 8361931
    Abstract: 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.
    Type: Grant
    Filed: January 4, 2012
    Date of Patent: January 29, 2013
    Inventors: Masoud Salavati-Niasari, Sima Alikhanzadeh-Arani
