| Shrnutí: | Title screen Interaction of lithium-titanium polycrystalline ferrites with ambient air during their sintering is investigated using the methods of electroconductivity and thermal gravimetry within the temperature interval T = 600-1300 K. It is found out that the temperatures exceeding T = 1100 K correspond to effective course of reducing reactions in this material, which results in the formation of an oxygen-deficient ceramic structure in the stage of isothermal tempering (T = 1280 K). It is shown that in the final cooling stage the process of exchange of the ferrite ceramics with the ambient atmosphere exhibits a pronounced oxidative character. The role of these redox processes in the formation of the oxygen non-stoichiometry of the sintered specimen and the depth of its distribution are analyzed.
