Abstract
Phase equilibria in the Li–Mn–Eu–O system were studied for the first time in the temperature range 700–1000°С, and a concentration diagram was plotted within the Li–Mn–Eu triangle at an oxygen partial pressure of 21 kPa. It is shown that the LiEuO2–Li2MnO3 system is quasi-binary, unlike the sections LiEuO2–LiMnO2 and LiEuO2–LiMn2O4. It has been established that, for spinel LiMn2O4 (Fd\(\bar {3}\)m), a homogeneous introduction of 2 mol % Eu is possible, while in the case of Li2MnO3 (C2/m), the single-phase state decays.
