Abstract

The standard enthalpies of formation (Delta H-f(298.15)0) of La5Ga3, LaGa and LaGa2 at 298.15 were determined by high temperature liquid gallium solution calorimetry to be -62.6+/-4.5, -74.8+/-3.7 and -69.0+/-3.7 kJ gatom(-1) respectively. The enthalpy of formation of LaxGa1-x where. x=0.19 at 1125K was determined by using precipitation calorimetry, to be -37.5+/-3.7 kJ gatom(-1). The partial enthalpy of solution of lanthanum in liquid gallium at infinite dilution (Delta(H) over bar (infinity)(La)) at 1099 K was determined to be -167.9+/-6.8 kJ gatom(-1).
