摘要：
The liquidus surface for the Al2O3-ZrO2-Yb2O3 phase diagram is constructed for the first time. No ternary compounds are found in the system. The liquidus surface is completed by seven primary crystallization fields. Two four-phase invariant eutectic equilibria, two four-phase invariant transition equilibria, and one three-phase invariant eutectic equilibrium are found in the ternary system. Since ZrO2 interacts with other phases eutectically, composite materials can combine the unique properties of ZrO2-based T-and F-phases with the properties of other phases of the Al2O3-ZrO2-Yb2O3 system.
