Abstract:
A ceria-zirconia-based composite oxide containing a composite oxide of ceria and zirconia is provided, in which primary particles having a particle diameter of 1.5 to 4.5 μm account for, on a particle number basis, at least 50% of all primary particles in the ceria-zirconia-based composite oxide, and the molar ratio of cerium to zirconium in the ceria-zirconia-based composite oxide is between 43:57 and 55:45.

Claim (Index 1):
A ceria-zirconia-based composite oxide comprising a composite oxide containing ceria and zirconia, wherein primary particles having a particle diameter of 1.5 to 4.5 \u03bcm in the ceria-zirconia-based composite oxide account for, on a particle number basis, at least 50% of all primary particles in the composite oxide, and a content ratio of cerium to zirconium in the ceria-zirconia-based composite oxide is in a range of 43:57 to 55:45 by mole ratio; and\n when heated for 5 hours in the atmosphere under a temperature condition of 1,100\u00b0 C. and thereafter examined by X-ray diffractometry using CuK\u03b1, the ceria-zirconia-based composite oxide exhibits an X-ray diffraction pattern in which an intensity ratio of diffraction line at a 2\u03b8 of 14.5\u00b0 to diffraction line at a 2\u03b8 of 29\u00b0 {I(14/29) value} and an intensity ratio of diffraction line at a 2\u03b8 of 28.5\u00b0 to diffraction line at a 2\u03b8 of 29\u00b0 {I(28/29) value} satisfy requirement I(14/29)\u22650.015 and I(28/29)\u22640.08.
