| Abstract: | This study provides an in‐depth overview of the methods for measuring thermal conductivity and diffusivity of solid and molten mold fluxes, focusing on the development, advantages, and disadvantages of stationary, non‐steady‐state, and transient methods. The study highlights the challenges associated with stationary and non‐steady‐state methods, such as large sample sizes, difficulty in maintaining constant‐temperature profiles, and effects of convection, radiation, and low thermal conductivity materials. It also emphasizes the benefits of transient methods, including short measurement times and low sample weights, which help preserve the initial chemical composition of the samples. Transient hot‐wire and laser‐flash methods are also discussed, along with their application, accuracy, and limitations. Detailed results of thermal conductivity and diffusivity measurements of slags are presented. This study is dedicated to Professor Seetharaman, who has worked extensively on measuring thermophysical properties, thereby contributing significantly to the study of mold fluxes.
