Metal Propionate Solutions for High-Throughput Liquid-Assisted Manufacturing of Superconducting REBa₂Cu₃O_7-δ (RE = Y, Gd, Sm, and Yb) Films.

ABSTRACT: The cost-effective synthesis of a series of metal propionate powders (copper, yttrium, barium, samarium, gadolinium, and ytterbium) is developed through single chemical reactions resulting in five novel crystalline forms. These complexes are valuable precursors for the preparation of epitaxial REBa₂Cu₃O_7-δ (REBCO) superconducting films (here, RE = Y, Sm, Gd, and Yb) through the innovative transient liquid-assisted growth (TLAG) process based on chemical solution deposition (CSD). TLAG-CSD shows impressive results with YBa₂Cu₃O_7-δ (YBCO), obtaining critical current densities of 2.6 MA/cm² (77 K) on 500 nm films at unprecedented growth rates (50-2000 nm/s), boosting unprecedented high-throughput industrial productio
