Fabrication of Filamentary YBCO Coated Conductor by Inkjet Printing

Inkjet printing is a potentially low cost, high rate method for depositing precursors for filamentary YBCO coated conductors. The method offers considerable flexibility of filament pattern, width, and thickness. Using standard solution precursors and RABiTS substrates, the printing, processing, and properties of some inkjet-derived filamentary YBCO coated conductors for second generation (2G) wire are demonstrated on a laboratory scale. Some systematic variations of growth rate and critical transport current with filament width are observed and discussed.
