STRUCTURE OF LITHIUM PYROSILICATE MELTS ACCORDING TO DATA OF HIGH-TEMPERATURE RAMAN SPECTROSCOPY

Olga N Koroleva, Tatyana V Mosunova

Abstract


Decomposition of the high-frequency range of Raman spectra for 60Li2O×40SiO2 melts (Li60) into the Gaussian line shape was performed. The basic structural fragments of melts and their ratio were determined, and the peculiarities of their interaction with the change in temperature were identified.

Keywords
