Abstract
A silicon carbide-based porous material characterized by comprising silicon carbide particles as an aggregate, metallic silicon and an oxide phase containing Si, Al and an alkaline earth metal; it is high in porosity and strength and superior in oxidation resistance and thermal shock resistance and, when used as a filter, is very low in risk of having defects such as cuts (which cause leakage of fluid) and the like, as well as in pressure loss.
