The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz.
Uses Of Silica Sand
Quartz sand is the major ingredient in virtually all types of glass. The
principal glass products include containers (bottles and jars), flat
glass (windows, mirrors), lighting glass (light bulbs, flourescent tubes),
TV tubes and screens, decorative glass, fiberglass.
Quartz sand is used for the preparation of: the form blends from
cast-iron, steels and nonferrous foundires, abrasive cleaning of
castings surfaces, as raw material for obtaining peliculizat sand.
Quartz sand that has been ground to fine size is an ingredient of most
clay bodies and is a major constituent of ceramic glazes. Typical
everyday products include tableware, sanitaryware, ornaments and wall and floor tiles.
Being the principal filtration environment in the water industry the silica
sand is used-up in water filtration stations, water wells or to prevent
The construction industry is founded on quartz sand and there are a
Host of specialist applications including silica and aerated concrete
Blocks, floor and roof tiles, flooring and rendering compounds, white
Markings, roofing felt and cement.
The quartz sand is a widely used product in manufacturing the adhesives used for: tiles, natural rock pavements, marble.
THE SILICATE OF SODIUM
The quartz sand is used for producing the silicate of sodium.
Silica has many other applications including the manufacture of chemicals and metals, fillers in numerous products, plastic, the manufacture of refractories, stimulating oil production
