A thermodynamic assessment of the In–Se system

Abstract Available experimental thermodynamic and phase diagram data were critically reviewed. A thermodynamic assessment of the binary In-Se system was performed based on the evaluation of literature. The intermediate compounds taken into account are In 4 Se 3 , InSe, In 6 Se 7 , In 9 Se 11 , In 5 Se 7 , and polymorphic In 2 Se 3 (α, β, γ and δ). All these compounds were treated as stoichiometric phases. The liquid phase was described using the association model with the associate species of ‘In 2 Se 3 ’. A set of thermodynamic parameters was obtained, and the calculated phase diagram is presented.
