A comparative study of in-situ mechanochemically synthesized Mn0.5Zn0.5Fe2O4 ferrite nanoparticles in the MnO/ZnO/Fe2O3 and MnO2/Zn/Fe2O3 systems

Mechanochemical synthesis of nanostructured and composite oxide ceramics: From mechanisms to tailored properties

“…Mn 1-x Zn x Fe 2 O 4 ceramic powder Among soft spinel ferrites, manganese-zinc ferrites are important electronic ceramic materials in electronic devices, and the presence of high resistivity and relatively high magnetic polarization makes these ferrites irreplaceable materials. 182,197,198 Hashim and coworkers 182 synthesized nanocrystalline Mn .5 Zn .5 Fe 2 O 4 spinel ferrite by mixing different zinc sources (Zn and ZnO) with MnO 2 and Fe 2 O 3 powders through mechanical chemistry. The reaction using Zn source is more exothermic than that of ZnO reaction system, which provides sufficient activation energy for the synthesis of Mn-Zn ferrite, and the average particle size of the synthesized ferrite is small.…”

“…For example, magnetically tuned filters can be made from BFO 164 . Powders of LiFe 5 O 8 and NiFe 2 O 4 ferrite 178–182 can be used in microwave technology, magnetic storage devices, sensor technology, and high‐density information storage media for medical diagnostic applications.…”
