The standard molar enthalpies of formation of PdAl, PtAl, ScAl_1.78, YAl₂ and LaAl₂ have been determined using a high-temperature calorimeter at 1473 ± 2 K: ΔH°_f(PdAl) = -182.5 ± 9.3 kJ mol^-1, ΔH°_f(PtAl) = -195.1 ± 10.1 kJ mol^-1, ΔH°_f(ScAl_1.78) = -132.6 ± 2.6 kJ mol^-1, ΔH°_f(YAl₂) = -151.2 ± 3.8 kJ mol^-1 and ΔH°_f(LaAl₂) = -149.6 ± 6.2 kJ mol^-1. Comparisons are made with some available data and with predicted values.
