ABSTRACT:
A silicon carbide porous object includes silicon carbide as an aggregate and metal silicon as a binder, the particles of silicon carbide being bonded to one another so as to have pores thereamong. A method for producing a silicon carbide porous object includes: firing raw materials formed by mixing silicon carbide and metal silicon with metal aluminum or an alloy including metal silicon and metal aluminum in an inert gas atmosphere or a reduced-pressure atmosphere to produce a metal aluminum-metal silicon-silicon carbide porous object; and oxidizing and firing the metal aluminum-metal silicon-silicon carbide porous object in an oxygen atmosphere.
