| description | •FeGe(s) and FeGe2(s) have been synthesized and characterized.•The heat of dissolutions of Fe(s), Ge(s), FeGe(s) and FeGe2(s) in liquid tin have been measured.•ΔfH298° of FeGe, FeGe2 were found to be to −15.56±0.92 and −36.89±1.17kJmol−1, respectively.
Thermodynamics plays an important role in predicting long term stability of the materials under different reactive conditions. The present paper describes determination of standard molar enthalpies of formation of FeGe(s) and FeGe2(s) compounds employing a high temperature solution calorimeter. The reaction enthalpies of Fe(s), Ge(s), FeGe(s) and FeGe2(s) in liquid Sn at 986K were measured using a Calvet calorimeter. The standard molar enthalpy of formation of the compounds at 298K (ΔfH298°) were calculated using the measured reaction enthalpy data. The values of ΔfH298° of FeGe(s) and FeGe2(s) at 298K were found to −15.56±0.92 and −36.89±1.17kJmol−1, respectively. The standard molar enthalpy of formation of FeGe(s) and FeGe2(s) at 298K obtained experimentally has been compared with the calculated values derived using Vienna ab initio simulation package (VASP). |
