Abstract:
The invention relates to a method for generating oxidic nanoparticles from a material forming oxide particles, com­prising the steps: preparation of an aqueous solution containing the ions of the material forming the oxide particles, film evaporation of the solution at a temperature above 200 °C and skimming off the nanoparticles floating on the surface of the aqueous solution generated in the vicinity of the vapour film on film evaporation.
Claim 1:
1. A method for coating a substrate with oxidic nanoparticles, with the step of: - providing an aqueous solution containing ions of a material that forms oxide particles, characterised bythe further steps of: - film boiling the solution at temperatures above 200°C, - immersing the substrate in the aqueous solution so that the areas of the substrate to be coated pass through the nanoparticles that have risen to the surface of the solution, and - withdrawing the coated substrate.
