The study investigates electro-migration in Li–Ti ferrite ceramic samples sintered in radiation-thermal mode. To reveal radiation effects, similar measurements are performed for samples sintered in thermal mode. The effect of the state of grain boundaries and the presence of a low-melting additive on electrical properties of sintered ferrites is studied. It is found that structural rearrangement during radiation-thermal sintering occurs in early sintering stages, including the heating period. Study demonstrates that such behavior associated with radiation-induced intensification of the liquid phase spreading over the array of powder grains. In addition, it was shown that structural transformation may be caused by stimulation of intergranular slippage
