Used extensively in glass manufacturing due to its high melting point and purity, providing the primary silica source for container, flat, and specialty glass. Plays a critical role in foundry operations as a molding material for metal castings because of its thermal stability and strength. Serves as a key component in construction, especially in concrete and mortar mixes, enhancing durability and structural integrity. Utilized in water filtration systems where its granular form acts as a physical barrier to remove suspended particles. Employed in oil and gas extraction as a proppant in hydraulic fracturing to keep fractures open and improve flow of oil and gas. Also used in agriculture as a soil conditioner to improve drainage and aeration in heavy soils.
