Physicochemical Analysis of The Composition and Structural Characteristics of Sodium Silicate Solutions

This study analyzes the composition and structural characteristics of sodium silicate solutions (water glass). The influence of the SiO₂/Na₂O ratio (silicate modulus) on polymerization degree, structural organization, and stability is examined. It is shown that these solutions have a colloidal-polymeric nature, forming structures from simple units to complex networks. The effects of pH, concentration, and temperature on structural changes and gelation processes are also considered. The results indicate that increasing the silicate modulus enhances polymerization, viscosity, and stability, which are important for industrial applications such as construction materials and adhesives.
