摘要：

The standard enthalpies of formation of nine thulium alloys with late transition metals have been determined by direct synthesis calorimetry at 1400+/-2 K. The following values of Delta H-f degrees (kJ(mol atom)(-1)) are reported: TmNi5, -29.1+/-0.7; TmRh, -88.9+/-2.0; TmRh2, -73.0+/-2.0; -92.6+/-2.0; Tm3Pd4, -93.0+/-1.7, TmPd3, -86.8+/-1.6, TmPt, -121.0+/-2.0; TmPt2, -112.4+/-3.1; TmPt3, -91.1+/-2.1. The results are compared with predicted values from the Miedema model and with available literature data for TmPd and TmPt.
