Исследование влияния механической активации исходных реагентов на твердофазный синтез литиевого феррита LiFeO2

Abstract

In this paper, the influence of mechanical activation of Li2CO3-Fe2O3 initial reagents on the nonisothermalsynthesis of LiFeO2 lithium ferrite was studied by TG/DSC methods. The mechanical activation wascarried out in AGO 2C planetary mill using steel vial and grinding balls for 60 minutes. It was shown that thepreliminary mechanical activation of Li2CO3-Fe2O3 mixtures increases the activity of the solid-phase reaction system that enables to significantly reduce the temperature of the thermal synthesis of LiFeO2 lithium ferrite.
