Used in the production of high-purity silicon and silica for semiconductor manufacturing and solar cells. Key precursor in the synthesis of fumed silica, which serves as a thickening agent in paints, coatings, and sealants. Employed in the manufacture of optical fibers due to its ability to form high-purity glass when hydrolyzed. Utilized in the surface treatment of metals and fillers to improve compatibility with polymers. Acts as an intermediate in the production of silane and other silicon-based chemicals used in electronics and construction materials.
