Abstract:
Provided is alumina material comprising alumina and zirconium, wherein in a radial distribution function obtained by Fourier-transforming an extended X-ray absorption fine structure (EXAFS) spectrum of a K absorption edge of the zirconium in the alumina material, the value of IB/IA is 0.5 or less where IA is a maximum intensity among the intensities of peaks present at 0.1 nm to 0.2 nm, and IB is a maximum intensity among the intensities of peaks present at 0.28 nm to 0.35 nm.
