摘要：

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: DELTA-H(f)-degrees (RuAl) = -(124.1 +/- 3.3) kJ/mol; DELTA-H(f)-degrees (RhAl) = -(212.6 +/- 3.2) kJ/mol; and DELTA-H(f)-degrees (IrAl) = -(185.5 +/- 3.5) kJ/mol. For OsAl, an approximate value is -77 kJ/mol- The results are compared with available data for related alloys and with predicted values.
