Abstract (en)
[origin: WO2009019234A1] The present invention relates to a method for producing a material suitable for producing ceramic oxide coatings, comprising the following steps: (a) preparing at least one first compound of a metal cation, selected from the cations of manganese, cerium, gadolinium, and/or yttrium, having at least one organic anion or an anion comprising an organic part, (b) dissolving or suspending the compound(s) prepared according to (a) in a protic, hydrolytically active solvent, such that the compound(s) is (are) present in a completely dissolved or colloidally dispersed form, (c) heating the suspension or solution thus formed in a closed vessel to at least 80°C, and (d) expanding and cooling the suspension or solution thus formed. Using said method, amorphous macromolecules are obtained, comprising molecular or polycyclic complexes having a primary particle size of <1 nm and an agglomerate size of 5 to 120 nm, preferably 10 to 80 nm. Applied to a substrate as a solution or suspension, said particles yield a coating material by means of which dense oxide coatings can be obtained even at relatively low temperatures.
