Title:
METHOD FOR PRODUCING HONEYCOMB STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/176897
Kind Code:
A1
Abstract:
This method for producing a honeycomb structure, e.g. for a heat exchanger, comprises: a moulding step for moulding a mixture containing silicon carbide particles, an organic component and a dispersion medium to obtain a moulded article; a degreasing step for removing the organic component included in the moulded article to obtain a honeycomb porous body; and an impregnation step for impregnating the interior of partition walls of the honeycomb porous body with metallic silicon. In the impregnation step, with the honeycomb porous body positioned inside a container, which contains solid metallic silicon, with a support therebetween, the inside of the container is heated to the melting point of metallic silicon or higher, and the honeycomb porous body is thereby impregnated with the molten metallic silicon via the porous support.
