It is an object to provide a method for producing titanium dioxide superfine particles, which produces monodispersed titanium dioxide superfine particles depending on its purpose, causes no clogging with a product due to self-dischargeability, requires no great pressure, and is excellent in productivity. In the method for producing titanium dioxide superfine particles in a fluid containing a titanium compound by separation, the fluid is formed into a thin film fluid between two processing surfaces arranged so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, and the titanium dioxide superfine particles are separated in the thin film fluid. |
