A comparative study of Ni {sub 0.7} Zn {sub 0.3} Fe {sub 2} O {sub 4} obtained by sol-gel auto-combustion and flash combustion methods

摘要: In this study, the nickel-zinc ferrites were prepared via two different methods: the sol-gel auto combustion method and the flash combustion method. Obtained reaction products were sintered at different temperatures 900, 1100 and 1300 Degree-Sign C. The structural and microstructural, as well as electric and dielectric properties of different samples were discussed. The synthesis method has a marked effect on crystalline order, grain size and its distribution, electrical resistivity and dielectric properties.
