Commonly found in small packets placed inside product containers to absorb moisture and extend shelf life. Also used in chromatography as a stationary phase for separating mixtures. Employed in catalyst supports, insulation materials, and as a thickening agent in paints and adhesives. Its high surface area and porosity make it effective for drying gases and liquids in industrial processes.
