Emissiveness of technical cadmium and zinc

The results of an experimental study of the normal integral and normal spectral emissivity of technical cadmium and zinc are presented. The choice of the objects of study was due to the lack of literature data on the emissivity of these metals in the open press. The measurements were carried out by the absolute radiation method in an inert gas atmosphere. The results of the change in the intensity of the normal integral emissivity depending on the temperature with the fixation of the surge in the phase transition region are obtained. The normal spectral emissivity of solid polished metals in the melting region was investigated from 0.26 to 10.6 μm. A computational experiment was conducted using the Foote and Drude approximations.
