Abstract
Disclosed is a composition for forming a thick oxide superconductor film, the oxide being an RE-BA—Cu based oxide, wherein RE is at least one element selected from the group consisting of Y, Nd, Sm, Gd, Eu, Yb, Pr, and Ho. The composition contains an RE salt of a keto acid having 4 to 8 carbon atoms as an RE component, barium trifluoroacetate as a Ba component, at least one copper salt selected from the group consisting of a copper salt of a branched saturated aliphatic carboxylic acid having 6 to 16 carbon atoms and a copper salt of an alicyclic carboxylic acid having 6 to 16 carbon atoms as a Cu component, and an organic solvent dissolving these metal salt components. In the composition, the RE to Ba to Cu molar ratio is 1:1.3 to 2.2:2.4 to 3.6 and the content of the organic solvent is 25% to 80% by weight.
