Thermodynamic Properties of Liquid Sn-Bi-Sb Alloys

摘要: Activity of tin in liquid Sn-Bi-Sb was derived by EMF measurement galvanic cell with fused salts electrolyte the temperature range 700 to 1000 K whole composition range. at 900 shows very small positive deviation from Raoult's law for SnBi alloys and moderately negative Sn-Sb alloys. ternary along SbyBi(1 －y)-Sn (y ＝0.25, 0.50 0.75) becomes large increasing Sb content. Excess free energy mixing is using Darken's method Gibbs-Duhem equation values are compared those model calculations based on three constitutive binary data. 論　文
