<p>The present invention concerns homogeneous aqueous solutions which are obtained from cheap reagents and contain the metallic cations necessary for the formation of a high-Tc-superconductor and one or more noble-metal cations such as Ag, Au or Pd for example. The invention also concerns the process for the exsiccating of said solutions and for the decomposition of the organic part, the exsiccates and the precursors prepared in said way and the composites obtained from these.</p> |
