Abstract:A low-cost and high-efficiency solid reaction method has been reported as an effective technology to synthesize manganese ferrite MnFe2O4 with a spinel crystal structure. This work clarified the underlying reason for the influence mechanism of SiO2 and Al2O3 on the synthesis of MnFe2O4. Synthetic MnFe2O4 polyhedral microparticles with a saturated magnetization of 71.19 emu/g, a ratio of saturation magnetization to residual magnetization (Ms/Mr) of 0.062 and a coercivity (Hc) of 6.50 Oe were successfully obtain… Show more
