Abstract
The present invention relates to a method for preparing nano-sized iron phosphate particles, the method including the steps of: mixing an iron salt solution and a phosphate solution in a reactor in order to prepare a suspension containing amorphous or crystalline iron phosphate precipitate; and applying a shearing force to the mixed solution inside the reactor during the step of mixing, wherein the suspension containing nano-sized iron phosphate precipitate particles is formed by means of the shearing force and the conditions inside the reactor. According to the present invention, micro-mixing takes place faster than nucleation, which provides an advantage for preparing nanoparticles and for preparing particles having a uniform particle size distribution.
