SynFoNY (Synthesis and Formulation of Nanoparticles for pinning in YBCO coated conductors)
Abstract
High-temperature superconducting materials as YBCO (YBa2Cu3O7-x) exhibit properties adequate for their use in power applications and magnets. The technology for their industrial manufacturing is already developed, with chemical solution deposition (CSD) as one of the most cost-effective approaches. However the performance of such materials is limited by vortex movement at medium to high magnetic fields. Those vortices can be immobilized by introducing artificial pinning centers (APCs), which have the ability to pin and restrict their movement. The spontaneous segregation of secondary phases during the YBCO heat treatment has already been described in literature. This approach has limitations in terms of nanocrystal formation and reaction control. For that reason, we have focused on the preparation of preformed nanocrystals as APCs. Here we present a powerful approach for the preparation of very small perovskite nanoparticles, with general formula ABO3. These inert materials are suitable for growing a high-quality YBCO film with nanocrystals homogeneously distributed on it. Ligand test screening has been performed to prepare stable colloidal solutions which have been successfully used for the deposition process.
