Abstract

The thermodynamic and structural aspects of the polyamorphic transition in yttrium and other rare earth aluminate liquids were analyzed. This transition was seen as the nucleation and growth of a low density phase in a matrix of a higher density liquid when Y2O3-Al2O3 liquids were cooled below the liquidus. A combination of DSC and solution calorimetry was used to evaluate the energetic differences between the two liquid phases of yttrium-aluminates.
