Abstract:
1. A method for producing porous ceramic layers on a metallic, a ceramic, an enameled or a glass substrate, said method comprising: mixing oxide, carbide, nitride or sulfide powder particles of a size between about 3 nm and about 100 nm with an oxycarboxylic acid and a combination of at least one solvent and at least one polymeric binder (or a combination of a monomer and a radical starter) to form a mixture having a solids content of nanoparticles of greater than about 30 percent by volume; applying the mixture onto the substrate by dip-coating, spin coating, immersion, flooding, spraying, screen printing or film casting; and drying and solidifying the applied mixture into a porous layer.
