摘要：

The standard enthalpies of formation (Delta(f)H(298.15)(0)) of Y5Ga3, YGa and YGa2 at 298.15 were determined by high temperature liquid gallium solution calorimetry to be -59.6+/-3.6, -68.9+/-2.8 and -64.4+/-2.5 kJ gatom(-1) respectively. The enthalpy of formation of YGa2 at 1125 K was determined by using precipitation calorimetry, to be -61.8+/-2.8. The partial enthalpy of solution of yttrium in liquid gallium at infinite dilution (Delta (H) over bar(y)(x)) was determined to be -184.4+/-5.3 kJ gatom(-1). (C) 2000 Elsevier Science S.A.
