Abstract:Miedima's theory has been applied to calculate systematically the mixing enthalpies of liquid binary alkaline metal alloys and the formation enthalpies of solid binary alkaline metal alloys. The calculated values for the liquid alloys are in good agreement with the experimental values available and those of the first-principle or ab initio calculations. For solid alloys, the present results are in reasonable agreement with those of the first-principle pseudopotential theory calculations.
