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}_fH^o_m(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.
