Abstract
The standard enthalpy of formation of Sc5Si3 has been determined by solute-solvent drop calorimetry at (1473±2) K. The following value is reported: ΔH of (mean)=−(719.1±34.0) kJ mol−1. This result is compared with corresponding published values for the enthalpies of formation of Me5Si3, with Me=Mn, Cr, V, Ti. This comparison shows regularly increasing negative enthalpies of formation from Mn5Si3 to Sc5Si3.
