Abstract
Official abstract text for this publication.
What is provided is a titanium oxide powder having a BET specific surface area of 300 m2/g to 480 m2/g as measured through a nitrogen adsorption method, an anatase content of a crystalline phase of 90% or more as measured through XRD measurement, and a spin-spin relaxation time T2 of 46 ms to 103 ms obtained by performing pulsed NMR measurement of a 5 mass % suspension prepared using ion exchange water.
First claim
Opening claim text (preview).
The invention claimed is: 1. A titanium oxide powder having a BET specific surface area of 300 m 2 /g to 480 m 2 /g as measured through a nitrogen adsorption method, an anatase content of a crystalline phase of 90% or more as measured through XRD measurement, and a spin-spin relaxation time T2 of 46 ms to 103 ms obtained by performing pulsed NMR measurement of a 5 mass % suspension prepared using ion exchange water. 2. The titanium oxide powder according to claim 1 , wherein a carbon content is 0.5 mass % or less. 3. The titanium oxide powder according to claim 1 , wherein a chlorine content is 0.1 mass % or less, a silicon content is 0.1 mass % or less, and a sulfur content is 0.1 mass % or less. 4. The titanium oxide powder according to claim 1 , wherein a half width of a diffraction peak with diffraction angles 2θ of 24.5° to 26.0° is 1.10° to 2.00°. 5. The titanium oxide powder according to claim 1 , having a zeta potential of −63 mV to −40 mV.
