MANUFACTURING METHOD OF UV LIGHT SHIELDING MATERIAL PARTICULATES, UV LIGHT SHIELDING MATERIAL PARTICULATE DISPERSOID USING UV LIGHT SHIELDING MATERIAL PARTICULATES, AND UV LIGHT SHIELDING BODY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of manufacturing UV light shielding material particulates having sufficiently suppressed optical catalytic activity and high UV light shielding property while having a simple catalytic activity suppression effect-imparting step, a UV light shielding material particulate dispersoid that uses the UV light shielding material particulates, and a UV light shielding body.SOLUTION: A manufacturing method of UV light shielding material particulates is provided, the method includes a step of depositing precipitates of a zinc oxide precursor by dropping an aqueous solution in which one kind or more of compounds containing a predetermined additive element is dissolved into an aqueous solution containing a predetermined zinc oxide precursor, a decantation step of cleansing the deposited precipitates, a step of forming a wet-processed product by wet-treating the precipitates after the cleansing with an alcoholic solution, and, after that, of obtaining a zinc oxide precursor treated powder containing the predetermined compound by drying the wet-treated product, and a step of obtaining UV-light shielding material particulates containing zinc oxide particulates in which, by heating the zinc oxide precursor treated powder under a predetermined atmosphere and under a predetermined temperature, a zinc element in a zinc oxide crystal is substituted with a predetermined element and is dissolved therein.SELECTED DRAWING: None
