摘要：

The enthalpies of mixing of the alloys of silver and gold with scandium, yttrium, and lanthanum have been measured by high-temperature reaction calorimetry at 1473 K. The standard enthalpies of formation of nine congruently melting intermetallic compounds in these systems (AgSc, Ag2Sc, AgY, Ag51 Y14, AgLa, Ag51La14, AuSc, AuY, and AuLa) also have been determined. All values are compared with the predictions of the semiempirical model of Miedema and co-workers.[14] A comparison between the data for the liquid alloys and for the intermetallic compounds provides approximate enthalpies and entropies of fusion for the considered compounds.
