First Claim
Patent Images
1. In a process for producing a ceramic layer including Bi as a component from at least a precursor containing Bi and a second precursor on a substrate, the improvement which comprises:
- using only an organic acid Cn H2n+1 COOH where n =0, 1 or 2 and, where appropriate, water as solvent for the precursors, and dissolving the precursor containing Bi in the solvent in the presence of the second precursor;
then applying the dissolved precursors to the substrate; and
then producing the layer by heating.

Abstract
A ceramic layer, in particular having ferroelectric, dielectric or superconducting properties, uses compounds with a simple structure as precursors and only methanoic acid, acetic acid or propionic acid and, where appropriate, water as solvent.
