Periodicity of the emissivity of V period metals in the region of melting temperatures

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 ( C p ). 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 C p 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.
