Abstract
For the moment, YBa2Cu3Ox (YBCO) remains the material of choice in the production of long length coated conductors. The coated conductor design which is most promising is based on a metallic Ni-5%W tape with a La2Zr2O7 – CeO2 buffer structure on top. In this work, the deposition of YBCO coatings on single crystal (SrTiO3) and on buffered NiW substrates using piezoelectric ink-jet printing (Dimatix Materials Printer and Microfab single-nozzle) was investigated. The combination of a chemical route with ink-jet printing gives some important advantages over traditional deposition techniques (e.g. spincoating) such as control of the waste of the precursor solution, production in long lengths and the possibility to switch quite easily from depositing a coating to a multifilamentary superconductor. The precursor solutions we use for printing YBCO layers are based on a fluorine-free sol-gel system containing metal acetates and using water as the primary solvent. The absence of fluor in the precursor solution simplifies and shortens the heat treatment. To maintain stability in the precursors, the influence of chelating agents such as triethanolamine and EDTA was explored. This study was specifically concerned with the optimization of the ink rheology and printing parameters necessary to obtain a well textured YBCO coating. After deposition of the aqueous film, an appropriate heat treatment was applied. The resulting ceramic films were analysed with optical microscopy, SEM and XRD. Superconducting properties of the YBCO films were investigated.
