Abstract

Disclosed are a silicon carbide-based porous body and a method of fabricating the same. The silicon carbide-based porous body is formed by burning silicon carbide-based particles, and includes Si-N- or Si-N-O-based acicular particles grown to have a needle shape on the surfaces defining the pores in the porous body. Further, the method of fabricating a silicon carbide-based porous body includes forming a pre-molded product using silicon carbide-based particles having a purity of 95% to 99%, and thermally treating the pre-molded product in a kiln in a nitrogen atmosphere having partial pressure of 0.5 atm to 2 atm, thus growing Si-N- or Si-N-O-based acicular particles having a needle shape on the surfaces defining the pores in the porous body.
