Silica sand, also known as quartz sand, is composed mainly of silicon dioxide (SiO). It is a naturally occurring mineral that is commonly used in a variety of industries due to its properties like durability, high melting point with low iron content , customization and resistance to weathering. Here are some common uses and facts about silica sand:
Common Uses:
Glass Manufacturing: Silica sand is a primary raw material in the production of glass, including container glass, flat glass, and specialty glass.
Construction: It is used in concrete, mortar, and other construction materials, as well as for sandblasting.
Foundries: Silica sand is used in foundry molds and cores for casting metal parts.
Water Filtration: The sand is used in water filtration systems because of its ability to trap contaminants.
Oil & Gas Industry: It is used in hydraulic fracturing (fracking) to prop open fractures in shale rock to extract oil and natural gas.
Sports & Leisure: Silica sand is used in products like sandboxes, golf course bunkers, and artificial turf.
Properties:
Hardness: Silica sand is known for its hardness, typically ranking around 7 on the Mohs scale, which makes it useful for many industrial applications.
Grain Size: The grain size of silica sand varies, with smaller grains being used for things like glass and larger grains being used for sandblasting or filtration.
Color: It can vary in color, from white to tan or even pink, depending on impurities and iron content.
