The Dependence of Gibbs Energy of Formation of Niobium Mononitride on its Composition and Temperature in the Range of 1773-2023 K

Abstract:

The article demonstrates the applicability of the interaction parameter method for describing the thermodynamic properties of non-stoichiometric niobium nitrides at temperatures of 1773 ± 2023 K. The authors obtained the equation of dependence of the nitride dissociation elasticity on its composition and temperature. They derived the expression for calculating Gibbs energy of formation of nitrides with a set composition, including stoichiometric, in the range of 1773 - 2023 K.
