A facile, anion‐induced, one‐pot solvothermal method was successfully developed to prepare two kinds of highly dispersed magnetic Fe 3 O 4 submicrometer spheres at 200°C in 12 h. The diameters of the as‐prepared Fe 3 O 4 submicrometer spheres are ~500 and ~200 nm, respectively. With the guidance of OAc − ions, the size and morphology of the Fe 3 O 4 spheres could be well controlled. The saturation magnetization of the Fe 3 O 4 spheres was measured to be 84 and 74 emu/g, respectively. The assembly of tiny precursor nuclei into the Fe 3 O 4 spheres relies on Ostwald ripening. The synthesized Fe 3 O 4 submicrometer spheres show good magnetic response, good water solubility, and uniform size.
