Abstract
Methods of X-ray phase analysis (XRPA) and differential thermogravimetry in a magnetic field (DTG(M)) are used to investigate the phase composition of Li 0.5(1-x)Fe 2.5-0.5x Zn x O 4 (x Zn = 0.2, 0.4, and 0.6) ferrite spinels synthesized at a temperature of 700 °C during 120 min by thermal annealing of a reagent mixture in a furnace and heating of the mixture using high-power beam of accelerated electrons with energy of 2.4 MeV. Thermal ferritization of all compositions leads to the formation of phases whose composition is close to simple monoferrites. Lithium-zinc ferrite phases are formed during annealing under electron irradiation. It is concluded that the rate of controllable diffusion interaction of monoferrite phases significantly increases under conditions of high-power electron irradiation.
