<p>A zirconia-containing inorganic fiber, characterized in that it comprises a composite oxide phase comprising a first phase having a silica component or silicon carbide as a main component and a second phase comprising zirconia, and the proportion of zirconia is gradually increased toward the surface of the fiber; and a method for producing the inorganic fiber. The zirconia-containing inorganic fiber is excellent in the resistance to oxidation and an alkali and exhibits excellent catalyst function and/or catalyst carrying function, and further has an improved strength.</p> |
