Title:
METHOD FOR PRODUCING OXIDE PARTICLES WITH CONTROLLED COLOR CHARACTERISTICS
Document Type and Number:
WIPO Patent Application WO/2017/209306
Kind Code:
A1
Abstract:
In order to provide a method for producing oxide particles with controlled color characteristics and also provide oxide particles with controlled color characteristics, the present invention provides a manufacturing method for oxide particles, said method characterized in that color characteristics of the oxide particles are controlled by controlling the ratio of M-OH bonds that are bonds between M and a hydroxyl group (OH), or the M-OH bond / M-O bond ratio, where M is oxygen or one or multiple different elements other than hydrogen contained in oxide particles selected from metal oxide particles and metalloid oxide particles. With the present invention, it is possible to provide oxide particles in which color characteristics such as reflectance, transmittance, molar extinction coefficient, hue or saturation are controlled by controlling the ratio of M-OH bonds included in the metal oxide particles or metalloid oxide particles, or the M-OH bond / M-O bond ratio.
