摘要： Nano-sized inorganic particles having uniform particle sizes and precisely controlled particle diameters have already been produced by synthesis in an organic solvent, but these nano-sized inorganic particles are hindered from dispersing in a polar solvent because of the adsorption of a long-chain fatty acid on the surfaces of the particles. Further, it was difficult to form nano-sized inorganic particles dispersible in a polar solvent by replacing the long-chain fatty acid coats. According to the invention, various surface-coated inorganic particles dispersible in polar solvents can be produced from fatty acid-coated inorganic particles by adding a temporary coating substance such as thiomalic acid to a nonpolar solvent containing fatty acid-coated inorganic particles dispersed therein to replace the fatty acid coats by the temporary coating substance, dispersing the inorganic particles coated with the temporary coating substance in a polar solvent, and then adding a coating substance dispersible in a polar solvent, e.g., citric acid to the obtained dispersion to replace the temporary coating substance coats covering the inorganic particles by the coating substance dispersible in a polar solvent.
