Silica sand, also known as quartz sand, is mainly composed of silica and is the main raw material for making glass.Silica sand has ordinary silica sand, refined silica sand and high-purity silica sand. Silica sand is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO2. The color of silica sand is milky white or colorless and translucent. Its hardness is 7. the particle size is between 0.02 mm and 3.35 mm, and it is insoluble in hydrogen fluoride. Acids other than acid have good chemical stability, electrical insulation and wear resistance.

3.Applications of quartz sand
Silica sand is an important industrial mineral raw material widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemicals, plastics, rubber, abrasives and other industries.
Glass: the main raw materials of flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and anti-radiation special glass.
ceramics and refractory materials: porcelain billets and glazes, kiln high silica bricks, ordinary silica bricks and silicon carbide and other raw materials.
Metallurgy: raw materials or additives and fluxes of silicon metal, ferrosilicon alloy and silicon aluminum alloy
rubber, plastic: filler (can improve wear resistance)
coating: filler (can improve the acid resistance of the coating)
