In situ INVESTIGATION OF THE SOLVATION IN THE DISPERSE SYSTEM Li2CO3-Na2CO3-K2CO3 MELT-NANOPOWDER MgO BY RAMAN SPECTROSCOPY
Abstract
The method of Raman spectroscopy is used to obtain in situ information on the interparticle interaction features Raman spectroscopy is used to obtain in situ information on the interparticle interaction features in the high-temperature disperse system Li2CO3-Na2CO3-K2CO3 melt-MgO nanopowder. This information is required to find the optimal operating environments for carbonate fuel cells. It is found that when magnesium oxide nanopowder is introduced into the carbonate melt, a change in the vibrational spectrum of the system occurs due to the solvation of the solid-phase particles by the ions of the salt melt.
