Abstract
Spectroscopic studies of molten electrolytes have been carried out for more than 50 years. The information available in the literature on the problems arising in high-temperature spectroscopic measurements of molten electrolytes, as well as methods and technical solutions to overcome them, and the design of optical heating cells used for these purposes is fragmentary. The purpose of this review is to summarize the information available in the literature on techniques and methods for high-temperature spectroscopic measurements of molten electrolytes. A description of various techniques used in spectroscopic studies of molten electrolytes, including IR transmission spectroscopy, reflection and emission spectroscopy, reflection-adsorption spectroscopy, spectroelectrochemical Raman and IR spectroscopy is presented. A description of the design of the corresponding optical heating cells is given, as well as examples of spectra obtained using them. The review is useful for researchers studying electrolyte melts and specialists developing medium-temperature chemical current sources based on them.
