Widely used as a desiccant, silica gel absorbs moisture to protect products from humidity damage. It is commonly found in packaging for electronics, pharmaceuticals, and food to extend shelf life and prevent mold or corrosion. In laboratories, it serves as a drying agent in air and gas streams. Silica gel is also used in chromatography for separating compounds and in controlled-release formulations for drugs. Due to its high surface area and stability, it supports catalysts in industrial reactions. Additionally, it is used in moisture-sensitive indicators, such as in humidity control devices and breathers for transformers.
