NiFe2O4 nanoparticles were successfully prepared at room temperature and atmospheric pressure by solution SHS method without adjusting pH values of reaction system. The results of XRD and TEM analysis showed the NiFe2O4 nanoparticles were spherical, and their average particle sizes were 10 nm. The as-prepared nanometer NiFe2O4 powder was calcined at 600℃, 750℃, 850℃, 950℃ and 1 050℃ for 2 h, respectively; their average diameters increased from 12 nm to 34 nm.
