摘要： In a titanium oxide powder of this invention, a ratio (IA/IR) of a peak intensity (IA) of anatase-type crystals to a peak intensity (IR) of rutile-type crystals as measured by X-ray diffractometry is 0.1 or less; particles contained in the powder have an average short-axis length from 10 to 50 nm and an average aspect ratio from 1 to 3; a ratio (A450/A320) of an absorbance A450 at a wavelength of 450 nm to an absorbance A320 at a wavelength of 320 nm is from 0.015 to 0.5; and the powder contains a nitrogen atom and a peak derived from the nitrogen atom is observed from 395 to 402 eV in ESCA (Electron Spectroscopy for Chemical Analysis) measurement. A titanium oxide powder is thus provided that contains rutile-type crystals as a main component and has an excellent UVA shielding effect, high safety for the human body, and good color tone.

摘要： With an aim to provide a method for producing an oxide particle with controlled color characteristics and also provide an oxide particle with controlled color characteristics, the present invention provides a method for producing an oxide particle, wherein the color characteristics of the oxide particle are controlled by controlling a ratio of an M-OH bond between an element (M) and a hydroxide group (OH) or an M-OH bond/M-O bond ratio, where the element (M) is one element or plural different elements other than oxygen or hydrogen included in the oxide particle selected from metal oxide particles and semi-metal oxide particles. According to the present invention, by controlling the M-OH bond or the M-OH bond/M-O bond ratio of the metal oxide particle or the semi-metal oxide particle, the oxide particle with controlled color characteristics of any of reflectance, transmittance, molar absorption coefficient, hue, and saturation can be provided.
