Abstract
In a method for producing a porous ceramic compound, a green layer is disposed onto a previously sintered ceramic substrate and is sintered with the previously sintered substrate at temperatures between 500° C. and 1300° C., wherein the green layer comprises exclusively ceramic particles having a particle size of x≦100 nm and the sintered green layer being a functional layer has a layer thickness of s≦2.5 μm. The functional layer produced in this method is flawless and fine-pored and therefore particularly suited for filtration processes.

Method for producing a multi-layer porous ceramic compound through sintering, by disposing of a flawless ceramic layer onto a sintered ceramic substrate wherein a green layer is disposed directly onto the surface of the sintered substrate, wherein the green layer contains nanoscale particles of a particle size of x≦100 nm and narrowly distributed grain size distribution, and the layer containing the nanoscale particles is disposed in a layer thickness s, which is greater than the roughness depth of the surface of the substrate is disposed onto the substrate and the layer thickness s of the disposed layer containing nanoscale particles has a layer thickness of s≦2.5 μm after sintering with the substrate at temperatures between 500° C. and 1300° C.
