Standard enthalpy of formation of Al 0.28Fe 0.72 at 298 K

Abstract

The standard enthalpy of formation Δ f H m,(298) for the compound Al 0.28Fe 0.72 has been determined with a Tian-Calvet calorimeter (Setaram), by dissolution in an aluminium bath at 800°C (1073 K). The single-phase alloy was prepared by levitation melting followed by annealing. The experimental value found is Δ f H m,(298)=−24 645±422 J/mol.
