Features of the Morphological Structure of Grains of Two-Component (Na₂O, SiO₂) Synthetic Raw Material for the Glass Industry

Abstract—The morphological structure of particles of a synthetic raw material for the glass industry obtained as a result of the physicochemical interaction of a quartz-containing crystalline raw material source and sodium hydroxide was studied. The formation of a developed, near-surface shell on the surface and cavities of quartz grains, containing elements of compounds containing O and Na, is established, which contributes to an increase in the kinetics of solid-phase reactions between Si and Na, which contain components of the glass charge.
