Discussion of “Normal Spectral Emissivity Measurement of Liquid Iron and Nickel Using Electromagnetic Levitation in Direct Current Magnetic Field.”

Abstract

This note corrects nonphysical Drude model parameters presented for molten iron and nickel. A comparison of the corrected Drude models with data published in the literature shows that a simple Drude form is inadequate to describe the optical properties of molten iron and nickel.
