Experimental data reveal changes in emissivity with temperature in chromium, indicating structural transformations.

This research aims to investigate how the emissivity of chromium changes with temperature, particularly during melting.
Conducted experiments to measure total hemispherical emissivity of chromium across varying temperatures
Analyzed changes in emissivity during the solid-liquid phase transition
Examined correlations between emissivity, heat capacity, and density
Applied the Foot approximation to describe the experimental findings
Identified distinct patterns in emissivity changes associated with temperature increases
Found a significant drop in emissivity during melting, linking it to electronic and structural changes
Confirmed correlations between emissivity, heat capacity, and density

Kosenkov et al. (2025) studied this question.
