Low-cost and commercially viable processes to fabricate coated conductors are necessary for
application in electric-power technologies. We demonstrate the chemical solution growth of
CeO2
buffer and YBCO layers on IBAD-YSZ/Hastelloy templates. Very good biaxially textured
CeO2
buffer layers can be formed by the chemical solution method using inorganic cerium nitrate
precursors. Through control of the solution molarity, very uniform, smooth, and dense
CeO2
buffer layers can be obtained. Subsequently, the YBCO films were deposited by metallorganic
deposition using the trifluoroacetic (TFA-MOD) method. High-critical-current-density
(Jc) YBCO films were obtained, with the transport current density of about
1.2 MA cm−2
(77 K, 0 T). The onset transition temperature is as high as 94.5 K, and the transition width
is about 1.3 K. Hence, the mature IBAD technique, combined with the low-cost solution
method, can provide a very promising robust process for fabrication of low-cost YBCO
coated conductor on a large scale.
