A liquid phase in the Al 2 O 3 ‐1 mol% TiO 2 ‐0.5 mol% NaO 1/2 composition is confirmed at ±1300°C by an electrical conductivity measurement. The ease of the method led to a study of the Al 2 O 3 ‐2 mol% CuO‐2 mol% TiO 2 system and to the geologically important detection of eutectics (peritectics) in rock materials.
