Key Points

This research aims to investigate how varying concentrations of aqueous ammonia influence the properties of silicon dioxide xerogels.
Conducted two-stage sol-gel synthesis of silicon dioxide.
Utilized aqueous ammonia solutions at mass concentrations of 0.8, 1, 2, 3, and 5% as catalysts.
Examined properties such as bulk density, specific surface area, and porosity.
Found that lower ammonia concentrations resulted in more microporous xerogels.
Observed changes in specific surface area and particle size distribution based on concentration.
