METHOD FOR PRODUCING HONEYCOMB STRUCTURED BODY, METHOD FOR PRODUCING SI-SIC-BASED COMPOSITE MATERIAL, AND HONEYCOMB STRUCTURED BODY

摘要

A honeycomb structured body (20) of the present invention includes a partition part (22) forming a plurality of cells (23). The honeycomb structured body is produced by a method for producing a honeycomb structured body including an embedding step of embedding, in pores of a porous honeycomb substrate having an SiC phase and an oxide phase containing an Si oxide, an embedding substrate containing a metal Si particle having a particle size smaller than the pore size of the pores and a metal Al particle having a particle size smaller than the pore size of the pores, and a melting step of heating the porous honeycomb substrate embedded with the embedding substrate in an inert atmosphere, and melting the metal Si particle and metal Al particle contained in the embedding substrate to form a metal phase containing metal Si and metal Al in the pores of the porous honeycomb substrate.
