Structured layers composed of crosslinked or crosslinkable metal-organic compounds, shaped bodies containing them as well as processes for producing them

Process for manufacturing a structured shaped body or a structured layer made of a mixed oxide from a combination of barium and titanium and wherein the mixed oxide shows piezoelectric or magnetic behavior after appropriate activation, the process comprising the steps of:

• (a) dissolving at least one metal compound of at least one metal selected from barium and titanium in an organic solvent and/or exchanging a ligand of at least one metal compound of at least one metal selected from barium and titanium for a stabilizing ligand, thereby forming a solution,
• (b) adding to the solution a ligand with at least one photochemically polymerizable group and at least one group that allows a stable complex formation, and further adding purely organic monomers carrying more than two polymerizable groups that are polymerizable through addition polymerization, and optionally further adding a metal acylate or a metal hydroxide dissolved or in a solid form to the solution, to thereby form a product comprising a sol
• (c) applying the sol on a substrate whereby the sol is at least one of (i) applied in structured form or (ii) any unexposed areas of the sol are removed after polymerization and the shaped body or the structured layer remains,
• (d) exposing the sol anisotropically in such a way that a polymerization of the photochemically polymerizable groups takes place in the exposed areas to form the structured shaped body or structured layer, and
• (e) sintering of the shaped body or the layer until removal of organic components,
• characterized in that step (b) takes place either without additional supporting measures or that this step is carried out by implementing a measure through which a reaction equilibrium is shifted towards the product.
