摘要：
The invention relates to the area of ceramics and to ceramic multilayer filters of the type used for separating gases. The aim of the invention is to provide ceramic multilayer filters which are more economical to produce. To this end, the inventive ceramic multilayer filters consist of at least two layers of different particle size, the particle surfaces of all of the ceramic particles being completely or partially perfused with a material and spot and/or surface joins being formed between particles. The invention also provides a method for producing ceramic multilayer filters of this type, according to which slips are produced from at least two ceramic powders of different particle size, the particles of said ceramic powders being perfused with a material or a material in powder form being added to the ceramic slips. One or more layers are formed from the slips and then dried. At least two layers are placed one above the other and/or joined to each other and together, are subjected to a temperature increase.
