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.
Claims11
A silicon carbide-based porous material comprising silicon carbide aggregate particles bonded by metallic silicon particles constituting necking portions between bonded silicon carbide aggregate particles, and an oxide phase present in and strengthening said necking portions and containing Si, Al and an alkaline earth metal.
