Temperature changes in RAMAN spectra frequencies in the glass-forming salt system KNO3 – Ca(NO3)2
Abstract
Temperature changes in RAMAN spectra frequencies in the glass-forming salt system KNO3 – Ca(NO3)2
Incoming article date: 26.06.2022Parameters indicating the appearance of a glass-forming molten mixture in the melts of the salt system Ca(NO3)2 - KNO3 at a molar ratio of components of 3:2 are shown. The nonlinearity of the change in frequencies and line widths in the Raman scattering spectra of the anion NO3 was detected, which indicates a structural transformation in the molten mixture that correlates with a change in the viscosity of the mixture.
