Abstract
(Mg0.95Zn0.05)2(Ti0.8Sn0.2)O4 powder was synthesized by a solid state reaction. Then, Ni0.4Zn0.6Fe2O4 was grown on the (Mg0.95Zn0.05)(Ti0.8Sn0.2)O4 particles in a hydrothermal environment to form a core-shell structure. (1-x)(Mg0.95Zn0.05)2(Ti0.8Sn0.2)O4@xNi0.4Zn0.6Fe2O4 composite ceramics were sintered at 1200 °C with these powders. XRD, SEM, TEM analyses indicated that high dense core-shell ceramics without any foreign phase were obtained. Different types of sharp interfaces were self-assembled owing to the minimization of direct elastic energy in the hydrothermal environment. The composites enjoy good magnetic and dielectric properties, especially, good microwave dielectric properties with high saturation magnetization when the ferrite content is 0.3-0.5. The results provided a powerful experimental basis for the sensor and transducer.
