MANUFACTURING PROCESS OF DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing process of a dispersion by which a dispersion of stable and highly pure powders containing a minimal amount of coarse particles is manufactured with a single pulverizing process in pulverizing solid particles having different average particle sizes and a dispersion obtained by the manufacturing process. SOLUTION: The manufacturing process of a dispersion containing a component (A) and a component (B) comprises step (I) in which the raw material of the component (A) and the raw material of the component (B) having an average particle size larger than that of the raw material of the component (A) are added to a solvent (C) not dissolving or hardly dissolving the component (A) but dissolving the component (B) to obtain a slurry containing the dissolved component (B), step (II) in which the slurry obtained in step (I) is dried to remove the solvent (C) and a dried product containing the component (A) and the component (B) is obtained and step (III) in which the dried product obtained in step (II) is added to a solvent (D) not dissolving or hardly dissolving the component (A) and the component (B) and the mixture is wet-pulverized.
