Widely used as a desiccant, silica gel absorbs moisture to protect products from humidity damage. It is commonly found in packaging for electronics, pharmaceuticals, food, and clothing to prevent spoilage, mold, and corrosion. In laboratories, it serves as a drying agent for gases and liquids. Silica gel is also used in chromatography as a stationary phase for separating compounds. Due to its high surface area and porous structure, it supports catalysts and is used in industrial processes for purification and adsorption. In some cases, it is employed in controlled release systems for drugs and pesticides.
