A brookite-form crystalline titanium oxide powder has a volume-standard median diameter in the range of 0.3 to 40 μm as measured by a laser diffraction particle size distribution meter, and contains a brookite-form crystal in an amount of 90% by mass or more as measured by a powder X-ray diffraction method. A method for producing a brookite-form crystalline titanium oxide powder comprises a preparation step of preparing a crystalline titanium oxyoxalate powder, and a heating step of heating the crystalline titanium oxyoxalate powder at a temperature of 550° C. to 820° C. |
