According to this method, a fatty acid of CnH.sub.2nO.sub.2 (n=5 to 14) is mixed with a plurality of metal sources selected from Zn, In, Sn, Sb, and Al, thereby fatty acid metal salts are obtained, subsequently the fatty acid metal salts are heated at 130° C. to 250° C., and a metal soap that is a precursor is obtained. This precursor is heated at 200° C. to 350° C., and metal oxide primary particles are dispersed in the precursor melt. To this dispersion liquid, a washing solvent having a δP value higher by 5 to 12 than the δP value of the Hansen solubility parameter of the final dispersing solvent is added, thereby the metal oxide primary particles are washed and agglomerated, metal oxide secondary particles are obtained, and then washing is repeated.

A process for removing lactic acid from an aqueous lactic acid-containing magnesium chloride solution, the weight ratio of magnesium chloride to lactic acid in the aqueous lactic acid-containing magnesium chloride solution being at least 1:1, the process including the steps of subjecting the aqueous lactic acid-containing magnesium chloride solution to an evaporation step, resulting in the formation of a slurry of MgC12.MgL2.4H2O in an aqueous magnesium chloride solution, then subjecting the slurry to a solid-liquid separation step, to separate the solid MgC12.MgL2.4H2O from the aqueous magnesium chloride solution, resulting in the removal of lactic acid from the aqueous lactic acid-containing magnesium chloride solution in the form of MgC12.MgL2.4H2O. The process makes it possible to efficiently remove lactic acid from aqueous lactic acid-containing magnesium chloride solutions, resulting in magnesium chloride solutions with a low lactic acid content which can be further processed as desired.
