Widely used as a desiccant to control humidity and prevent moisture damage in packaging of electronics, pharmaceuticals, and food products. Effective in preserving moisture-sensitive items during storage and transportation. Commonly found in small packets labeled "Do not eat" inside shoe boxes, medicine bottles, and electronic devices. Also used in chromatography as a stationary phase for separating mixtures in laboratory settings. Employed in catalyst support due to its high surface area and stability. Used in air drying systems and as a moisture absorber in fuel systems and industrial equipment.
