Used extensively in glass manufacturing due to its high melting point and purity, providing the primary silica source for container, flat, and specialty glass. A key component in foundry casting, where it forms molds for metal parts because of its thermal stability and ability to retain shape under high temperatures. Employed in construction as a primary ingredient in concrete and mortar, enhancing strength and durability of structural materials. Utilized in the production of silicon metal and ferrosilicon alloys through high-temperature reduction processes in electric arc furnaces. Serves as a filtration medium in water treatment systems, effectively removing impurities and suspended solids from drinking water and wastewater. Applied in hydraulic fracturing (fracking) of oil and gas wells, where it props open fractures in rock formations to allow hydrocarbon flow. Used in landscaping and turf management as a soil amendment to improve drainage and aeration in sports fields and golf courses. Acts as an abrasive in sandblasting operations for cleaning, smoothing, or preparing surfaces in industrial maintenance and metalworking.
