Enthalpy increment measurements from 4.5 K to 350 K and the thermodynamic properties of the titanium silicide Ti₅Si₃(cr)

Enthalpy increments for Ti₅Si₃(cr) were measured from 4.5 K to 350 K with an adiabatic calorimeter. From a representation of these measurements the enthalpy relative to 0 K, the entropy, and the heat capacity of Ti₅Si₃(cr) to 350 K were calculated. Values of the Debye temperature, Θ_D, and the coefficient for the heat capacity of the conduction electrons, γ_el, were determined from the model. Thermodynamic properties for formation from the elements at 298.15 K were also given. Our previous value of Θ_Dfor TiSi₂ was revised due to improvement in the method of representation.
