Synthesis of MnZn ferrite nanoscale particles by hydrothermal method

Abstract

Hydrothermal method was used to synthesize nanoscale particles of MnZn ferrites. The crystallites were characterized by XRD, TEM and SEM. The effects of the reaction time, temperature and additives on the product were investigated. Crystallization process would be carried out above 160 °C for 5 h or more, higher temperature can reduce the reaction time. Additives were used to remove impurities such as Fe2O3, ZnMnO3. 10–15 nm pure slightly agglomerated MnZn ferrite crystallites with a narrow grain size distribution were obtained.
