た。(Prior Art) Sintered bodies such as alumina, zirconia, and silica have high strength and hardness, and also have good dimensional stability and are widely used as materials with excellent heat resistance and chemical resistance. In addition, porous bodies made of these materials are being used for filtering materials, catalyst carriers, sensors, etc. due to their excellent properties. However, oxide-based sintered bodies such as alumina and zirconia have drawbacks such as poor impact resistance and toughness, and are easily cracked or chipped, so that their uses have been limited.

が得られていないのが現状である。Conventionally, strengthening with non-oxide whiskers has been attempted as a method of imparting toughness to oxide-based sintered bodies, but sintering is performed in a non-oxidizing atmosphere such as nitrogen, argon, or vacuum. This has not been done in an oxidizing atmosphere where the whiskers change into oxides and the reinforcing effect is difficult to develop. In addition, in order to ensure the adhesion between the matrix matrix and the whiskers, the sintering method generally uses the hot press method or the HIP (hot isostatic pressing) method.
These methods increase the density of the matrix and are not suitable for manufacturing porous bodies, and ceramic porous bodies with excellent impact resistance and toughness have not yet been produced. is the current situation.
