    摘要: A highly functional film-coated powder which is produced without using the method based on the hydrolysis of a metal alkoxide and without using a metal alkoxide, which is an expensive compound, or a highly flammable organic solvent and which therefore can be obtained at a low overall product cost without necessitating explosion-proof facilities in the production equipment and while attaining easy temperature and humidity regulation; and a process for producing the same. The film-coated powder comprises a base particle having films on the surface thereof, wherein at least one of the films is formed by reaction of a metal salt in an aqueous solvent having a constant pH. By the technique, the surface of base particle can be evenly coated with a solid phase film while inhibiting particle aggregation without precipitating an independent solid phase in the liquid phase.
