Physicochemical methods are used to study the phase equilibria during crystallization of alloys in the Al2O3–HfO2–La2O3 system for the first time. Liquidus and solidus projections onto the concentration triangle, a melting diagram, and a crystallization scheme are constructed. No new ternary compounds and appreciable ranges of ternary solid solutions are found in the system.
