Abstract
This paper considers a relation between the emissivity of metals from the V period in Periodic Table while melting process with thermophysical properties surface tension coefficient (γ) and specific heat capacity (Cp). Taking the produced and available experimental data and using the theoretical calculation within Foot’s approximation, we elucidated the laws for emissivity as a function of electronic stricture and interatomic interaction. It was demonstrated that a correlation between the emissivity and parameters γ and Cp has a complicated behavior and this is dictated by general trends (emissivity increases with γ) and by a specific electronic configuration for the given elements. The results underline the importance of considering the periodicity and electronic configuration in forecasting the thermophysical properties of metals in the phase-transition state.
