Silica gel is extensively used in various fields. For instance, in the packaging industry, silica gel desiccants help absorb moisture from the air, protecting electronics, food, and pharmaceuticals from humidity. In the chemical industry, it serves as a catalyst carrier. In the medical field, silica gel can act as a matrix for drug delivery. Additionally, it plays crucial roles in air purification, liquid filtration, and laboratory analysis.

When using silica gel, it is essential to avoid direct contact with water, as this can reduce its adsorption efficiency. Spent silica gel can be regenerated through heating, making it reusable. This eco-friendly characteristic makes it an indispensable material in numerous industries.
