A variety of solution deposition routes have been reported for processing complex perovskite‐based materials such as ferroelectric oxides and conductive electrode oxides, due to ease of incorporating multiple elements, control of chemical stoichiometry, and feasibility for large area deposition. Here, we report an extension of these methods toward long length, epitaxial film solution deposition routes to enable biaxially oriented YBa 2 Cu 3 O 7−δ (YBCO)‐coated conductors for superconducting transmission wires. Recent results are presented detailing an all‐solution deposition approach to YBCO‐coated conductors with critical current densities J c (77 K)>1 MA/cm 2 on rolling‐assisted, biaxially textured, (200)‐oriented Ni–W alloy tapes. Solution‐deposition methods such as this approach and those of other research groups appear to have promise to compete with vapor phase methods for superconductor electrical properties, with potential advantages for large area deposition and low cost/kA·m of wire.
