Patent ID: 8745856

Claim:
A method for producing a ceramic filter element, comprising the steps of: applying structural elements onto an exterior surface of the ceramic filter element during generation of a ceramic body of the ceramic filter element by the steps of: providing a combustible non-ceramic paper-like material sheet material; rolling or winding together one or several layers of the combustible paper-like material to form a wound filter; introducing the wound filter into a carrier that provides a negative mold pattern of the structural elements to be formed so that on an exterior of the wound filter the structural elements to be formed are defined; impregnating the wound filter with a ceramic slip so that the ceramic slip is displaced by the negative mold pattern of the carrier; removing the carrier from the wound filter; sintering the impregnated wound filter, removing the paper-like material by combustion and forming a rigid sintered ceramic filter element having the structural elements thereon.
