A PROCESS FOR MAKING NANO-SIZED IRON PHOSPHATE PARTICLE

摘要

The present invention relates to a production method of nano-sized iron phosphate particles. The present invention comprises the following steps: a step of mixing an iron salt solution and a phosphate solution in a reactor for producing suspension containing amorphous or crystalline iron phosphate precipitates; and a step of applying shearing force to the mixed solution insdie the reactor during the mixing step. The suspension containing the nano-sized iron phosphate precipitates is produced by the shearing force and the condition inside the reactor. According to the present invention, a nucleation step is performed faster than a micro-mixing step for easily producing nanoparticles, and producing particles with uniform distribution.
