摘要： With an aim to 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 M-OH bond/M-O bond ratio, which is a ratio of a M-OH bond between an element (M) and a hydroxide group (OH) to a ratio of an M-O bond between the element (M) and oxygen (O), where the element (M) is one 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/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.

摘要： The present invention addresses the problem of providing a method for producing microparticles having a controlled crystallite diameter. At least two types of fluids to be processed; i.e., a raw material fluid containing a substance to be separated, and a separating fluid containing a substance for causing separation of the substance to be separated, are mixed in a thin film fluid formed between at least two processing surfaces which are approachably and separably disposed facing each other. At least one processing surface rotates relative to the other, and the substance to be separated giving a controlled crystallite diameter is caused to separate. At this time, specific conditions related to the fluid to be processed introduced between the processing surfaces are varied to control the crystallite diameter of the substance to be separated. The specific conditions are at least two conditions selected from the group consisting of: the type of substance to be separated included in the raw material fluid and/ or substance included in the separating fluid; the concentration of the substance to be separated included in the raw material fluid and/ or substance included in the separating fluid; the pH of the raw material fluid and / or separating material fluid; the introduction temperature of the raw material fluid and/ or separating fluid; and the introduction velocity of the raw material fluid and/ or separating fluid.

摘要： The object of the present invention is to provide a coloring ultraviolet protective agent in which the average molar absorption coefficient in the wavelength range from 200 nm to 380 nm is increased, and the color characteristics in the visible region are controlled. The present invention provides a coloring ultraviolet protective agent, which is useful for shielding ultraviolet rays and coloring, wherein the coloring ultraviolet protective agent comprises M2 doped oxide particles in which oxide particles (M1Ox) comprising at least M1 being a metal element or metalloid element, are doped with at least one M2 selected from metal elements or metalloid elements other than M1, wherein x is an arbitrary positive number, wherein an average molar absorption coefficient in the wavelength range of 200 nm to 380 nm of a dispersion in which the M2 doped oxide particles are dispersed in a dispersion medium, is improved as compared with one of a dispersion in which the oxide particles (M1Ox) are dispersed in a dispersion medium, and wherein a hue or chroma of color characteristics in the visible region of the M2 doped oxide particles is controlled.
