Abstract:
A titanium hydroxide having(i) a primary differential spectrum of radial structure function obtained from an extended X-ray absorption fine structure spectrum of titanium K absorption edge, the primary differential spectrum having two or more maximal intensities and two or more minimal intensities at interatomic distances in the range of from 1.4 Ã¥ to 2.8 Ã¥, at least two maximal intensities being at an interatomic distance of from 1.4 Ã¥ to 1.7 Ã¥ and at an interatomic distance of from 2.2 Ã¥ to 2.5 Ã¥, respectively, and at least two minimal intensities being at an interatomic distance of from 1.9 Ã¥ to 2.2 Ã¥ and at the interatomic distance of from 2.5 Ã¥ to 2.8 Ã¥, respectively; and (ii) index X calculated by the equation: X=(U2âˆ’L2)/(U1âˆ’L1) of about 0.06 or more, wherein U1 and U2 represent the maximal-intensity values at the interatomic distance of from 1.4 Ã¥ to 1.7 Ã¥ and at the interatomic distance of from 2.2 Ã¥ to 2.5 Ã¥, respectively, and L1 and L2 represent the minimal-intensity values at the interatomic distance of from 1.9 Ã¥ to 2.2 Ã¥ and at the interatomic distance of from 2.5 Ã¥ to 2.8 Ã¥, respectively, of the primary differential spectrum.
