A thermodynamic assessment of the In-Se system

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 In₄Se₃, InSe, In₆Se₇, In₉Se₁₁, In₅Se₇, and polymorphic In₂Se₃ (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 'In₂Se₃'. A set of thermodynamic parameters was obtained, and the calculated phase diagram is presented.
