Abstract

A premixed powdery precursor composition suitable as precursor material for obtaining a coating solution for the preparation of, for instance, thin film superconductors based on YBCO 1:2:3 via a coating technique, wherein the powdery precursor composition comprises a mixture of suitable salts of the constituent elements, in particular salts of trifluoroacetate and acetate.
