摘　　要：在超声波辐射下,用前驱体法合成了纳米铁酸锰(MnFe2O4)粉末。超声辐射MnCl2·4H20、FeCl3·6H2O和脲得到前驱体,再在950℃烘15 h制得平均粒径约35 nm的纳米MnFe2O4粉末。得到的纳米MnFe2O4粉末用X射线衍射(XRD),透射电镜(TEM),傅里叶转换红外光谱(FT-IR)进行表征并得到确认;产品磁学参数用样品振动磁强计进行了测定。Nanosized MnFe2O4 was synthesized with the aid of ultrasound radiation by a precursor approach. Sonicating an aqueous solution of MnCl2·4H2O, FeCl3·6H2O and urea yielded a precursor which produced nanosized MnFe204 particles with average particles size of 35 nm after heating at 950 ℃ for 15 h. The nanosized MnFe2O4 particles were characterized by powder X-ray diffraction, Transmission electron microscopy, FT-IR and VSM spectroscopy.
