The nature of phase equilibria in the Al2O3–TiO2–Er2O3 system at 1400°C is established and shown in the isothermal section of the phase diagram at this temperature. The interaction in the system is determined by compound Er2Ti2O7, which participates in equilibria with most phases of the system and determines its triangulation. No new phases or appreciable solubility regions based on components and binary compounds are found in the system. Ternary eutectic points are expected in the three-phase regions and binary eutectic points in the quasibinary sections.
