High energy effect in Li-Ti-Zn ferrite syntesis

Abstract

Lithium-zinc-titanium ferrite synthesis under the high energy action, including mechanical activation of initial reagents mixture in a planetary mill and subsequent heating of reaction mixture by a high-energy electron beam, is investigated using x-ray diffraction and thermal analyzes. The composition of initial reagents mixture corresponds to lithium substituted ferrite formation with a stoichiometric spinel formula: Li<inf>0.65</inf>Fe<inf>1.6</inf>Ti<inf>0.5</inf>Zn<inf>0.2</inf>Mn<inf>0.05</inf>O<inf>4</inf>. The synthesized ferrites were examined by saturation magnetization and Curie temperature measurements. It was shown that the mechanical activation for 60 min and radiation-thermal heating at 800°C of the initial reagents mixture significantly increase the reactivity of solid phase systems, and thereby, decrease the temperature and time of synthesis, improving the homogeneity of the end product. The obtained lithium-titanium-zinc ferrites are characterized by the high values of both the specific magnetization and Curie temperature.
