摘要：
A projection has been constructed for the liquidus surface on the plane of the concentration triangle for the Al2O3 - ZrO2 - Sm2O3 phase diagram. There are no ternary compounds, or appreciable regions of solid solutions based on the components and the binary compounds. The liquidus surface is formed by nine fields of primary phase crystallization. There are five four-phase nonvariant peritectic equilibria, as well as two four-phase nonvariant eutectic equilibria, and one three-phase nonvariant eutectic equilibrium. As the ZrO2 and SmAlO3 phases interact with other phases by a eutectic mechanism, it is possible to combine the unique properties of the T and F solid solutions based on ZrO2 with the properties of the other phases in the form of composites.
