    • The present invention relates to a method of synthesizing soft magnetic Ni-Zn ferrite nanoparticles with different Ni-Zn contents. The method comprises preparing an aqueous solution of zinc salt, an aqueous solution of nickel salt and an aqueous solution of iron salt in stoichiometric amounts. The aqueous solutions of zinc salt, nickel salt and iron salt are dispersed into an aqueous solution of a polymer and a sugar at a predetermined temperature under constant stirring to obtain a homogeneous mixture. A solid mass of polymer precursor powder is obtained at a predetermined pH by drying the reaction mixture in a microwave oven. Recrystallized nanoparticles of Ni-Zn ferrites (NixZn1-xFe2O4 (x = 0.2-0.8)) are obtained by heating the polymer precursor powders at 400-600°C in ambient air.
    • 本发明涉及具有不同Ni-Zn含量的软磁Ni-Zn铁氧体纳米颗粒的合成方法。 该方法包括制备化学计量量的锌盐水溶液,镍盐水溶液和铁盐水溶液。 在恒定搅拌下,将锌盐,镍盐和铁盐的水溶液在预定温度下分散到聚合物和糖的水溶液中以获得均匀的混合物。 通过在微波炉中干燥反应混合物,在预定的pH下获得固体块聚合物前体粉末。 通过在400-600℃在环境空气中加热聚合物前体粉末获得Ni-Zn铁氧体(NixZn1-xFe2O4(x = 0.2-0.8))的再结晶纳米颗粒。
