Silicon dioxide, also known as silica, is a naturally occurring compound commonly found in sand, quartz, and other minerals. It is widely used in various industrial applications, including as a key component in the production of glass, ceramics, and concrete. Additionally, it is utilized in the manufacturing of semiconductors, optical fibers, and abrasives. In the food and pharmaceutical industries, silicon dioxide is employed as an anti-caking agent and as an additive in powdered products to prevent clumping. Furthermore, it serves as a desiccant to control humidity and moisture levels in a variety of products.
