This paper presents experimental data on the normal total hemispherical emissivity (ε) of chromium over a wide temperature range, including the solid–liquid phase transition. The patterns of change in ε have been established, reflecting the rearrangement of the metal’s electronic structure upon heating and melting. The applicability of the Foot approximation for describing the experimental data was analyzed, and correlations between ε, heat capacity, and density were identified. It is shown that the abrupt change in ε during melting is associated with electronic and structural transformations. The obtained results refine the understanding of the radiative properties of chromium and can be used for modeling radiative heat transfer processes.
