The Calculation of Thermodynamic Properties of Ga-Sb Binary Liquid Alloys

In this paper, the activities of componentsof Ga-Sb system have been calculated from itsphase diagram by using computer program CABPD(calculating activities from binary phasediagrams) presented by us in previous paper.The excess free energy of liquid solution canbe expressed as:ΔG_m=X_(Ga)X_(Sb)(4392+17022X_(Sb)-15138X_(Sb)) J/mol In order to verify the reliability ofcalculated results, a discriminant has beenproposed.
