Abstract
Provided are a silicon carbide-based porous article comprising silicon carbide particles as an aggregate, metallic silicon and an aggregate derived from organometallic compound particles to form pores through volume shrinkage due to decomposition/conversion by heat treatment; and a method for producing the silicon carbide-based porous article, comprising, adding organometallic compound particles to form pores through volume shrinkage due to decomposition/conversion by heat treatment to a raw-material mixture containing silicon carbide particles and metallic silicon, then forming into an intended shape, calcinating and/or firing the resultant green body, forming pores through volume shrinkage due to decomposition/conversion of the organometallic compound particles, and the decomposed/converted substance of the organometallic compound particles being present as an aggregate in the porous article.
