الملخص:Title screen
The influence of mechanical activation of the Li2CO3–Fe2O3 initial reagents on ferrite phase formation in lithium ferrite LiFe5O8 is investigated. Methods of x-ray powder diffraction (XRD) and thermomagnetometry with differential scanning calorimetry (TG(M)/DSC) are used to compare the efficiency of nonisothermal synthesis at identical temperatures and burning times of the initial and mechanically activated reagent mixtures. It is demonstrated that preliminary mechanical activation of the initial Li2CO3–Fe2O3 reagent mixture considerably increases the reactivity of the solid phase system, thereby allowing the temperature of the thermal synthesis of lithium ferrite LiFe5O8 to be decreased significantly.
