Low temperature sintering of laminated Ni0.5Ti0.5NbO4-Ni0.8Zn0.2Fe2O4 composites for high frequency applications

The laminated magneto-dielectric composites of Ni0.5Ti0.5NbO4(NTN)-Ni0.8Zn0.2Fe2O4(NZO) were prepared by the conventional solid-state sintering method. The phase composition, microstructure, dielectric and magnetic properties of the composites were investigated. The results show that the as prepared composites are very dense and the NTN and NZO phases can coexist in the composites without any secondary phase. The as-prepared composites also exhibit excellent dielectric and magnetic properties in the frequency range from 10 MHz to 1 GHz, which make them have potential applications for high-frequency electronic devices.
