Description

The standard molar enthalpies of formation of RuAl, RhAl, and IrAl have been determined by the direct combination method using a high-temperature calorimeter operated at (1473 ± 2) K. The following values are reported: ΔH0f(RuAl) = -(124.1 ± 3.3) kJ/mol; ΔH0f(RhAl) = -(212.6 ± 3.2) kJ/mol; and ΔH0f(IrAl) = -(185.5 ± 3.5) kJ/mol. For OsAl, an approximate values is -77 kJ/mol. IN this paper, the results are compared with available data for related alloys and with predicted values
