An advanced low-fluorine GdBa2Cu3 O7-x (GBCO) precursor solution was prepared using barium, gadolinium, and copper acetates as starting materials; lactic acid, methacrylic acid, and trifluoroacetic acid as additives; and methanol as a solvent. The gel-film cast from this solution consisted of Gd trifluoroacetate and fluorine-free Ba and Cu salts. The BaCO3-free precursor was obtained through the pyrolysis of the gel film. After firing at 820 °C, the precursor was finally transformed to a phase-pure GBCO film. The critical current density (Jc) of the GBCO film was measured to reach 3.3 MA/cm2 (at 77 K, 0 T), and its critical transition temperature (Tc) was 92.6 K. During the pyrolyzing of the film, the relatively small amount of released fluorinated gases resulted in the rapid fabrication of GBCO film.
