Abstract
The present invention aims to provide a method of producing a fine particulate inorganic oxide dispersion, which makes it possible to easily disperse a fine particulate inorganic oxide while reducing the amount of dispersant used. The present invention relates to a method of producing a fine particulate inorganic oxide dispersion, the method including mixing the following components (A) to (D): (A) at least one fine particulate inorganic oxide selected from the group consisting of zirconium oxide (ZrO), titanium oxide (TiO), and barium titanate (BaTiO), (B) a dispersant, (C) an alkoxysilane compound, and (D) a solvent having the following Hansen solubility parameters: a hydrogen bonding component (dH) of 11 or less and a polar component (dP) of 4 or more; and wet grinding the resulting mixture.
