Structural Alteration Of Sodium-Aluminosilicate Glass Batch Using High-Temperature Raman Spectroscopy

In glass melting processes, homogeneous glass melt is formed from the batch via various chemical and physical processes; dehydration, solid-state reactions between raw material particles, forming melt phases, atomic diffusion and mass flow etc. This study pursues the alternation of materials from glass batch to molten glass in atomic level using Raman spectroscopy. The target composition is sodium-aluminosilicate glass system shown by 33Na2O-xAl2O3-(67-x)SiO2 in mol%, where x=0, 4, 8, 12 and 16, and the sample glasses are labelled as NAS00x.
