Abstract

Fluorine bomb combustion calorimetric measurements of the energy of the reaction: V3Si(cr) + (19/2)F2(g) = 3VF5(g) + SiF4(g), have given a value of -(163.3 ± 6.9) kJ.mol-1 for the standard molar enthalpy of formation {Δ}fHom(V3Si, cr) at T = 298.15 K and p = 101.325 kPa. This result is compared with others from the literature. A table is also given of the reassessed conventional chemical thermodynamic properties of V3Si from T = 298.15 K to T = 1700 K.
