Low cost Y-Ba-Cu-O coated conductors

Solution-based techniques have been examined as potential low-cost processes for manufacturing YBCO coated conductors. YBCO films prepared from metal trifluoroacetate precursors have achieved performance levels equaling or exceeding that of vapor deposited films with the same thickness on CeO2/YSZ(sc) substrates. J(c)'s of 4.5 MA/cm(2) and 2 MA/cm(2) have been achieved in 0.4 mum thick YBCO films on CeO2/YSZ(sc) and CeO2/YSZ/CeO2/Ni substrates, respectively. Textured Gd2O3 buffer layers have been deposited on deformation textured Ni substrates in a reel-to-reel process. The performance of YBCO films deposited on substrates containing the Gd2O3 seed layers is comparable in performance to YBCO films grown on all vacuum deposited buffer layers.
