Silica Sand

Listing ID #4004694

Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications. Silica sand is used in industrial processing, to make glass, as fill, and to create molds and castings.

Silica sand is produced by crushing sand stone or quartzite of open texture, and washing and garding it to yield requisite grain distribution. Silica flour is produced by crushing grinding and washing the high grade quartz, quartzite rocks or from white silica sand.

•  SALIENT FEATURES
•  Silica Sandstone is moisture free, fritable & hard.
•  Grain size of the particles is variable.
•  Friable & mainly brown to grey in colour.

•  APPLICATIONS
•  Glass - Silica is the major ingredient in virtually all types of glass. The principal glass products include containers (bottles and jars), flat glass (windows, mirrors, vehicle glazing etc.), lighting glass (light bulbs, fluorescent tubes, etc.), tableware (lead crystal, drinking glasses etc.), TV tubes and screens, decorative glass, fibreglass, optical glass and vacuum flasks.
•  Foundry Casting - Silica has a high melting point, 1610 degrees C. This enables castings to be produced by pouring molten metal into moulds made out of silica sand.
•  Ceramics - Silica 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.
•  Filtration - Closely sized grades of silica sand is the principal filtration medium used by the water industry to extract solids from wastewater.
•  Specialist Building Applications - The construction industry is founded on silica and there are a host of specialist applications including silica and aerated concrete blocks, floor and roof tiles, flooring and rendering compounds, white line markings, roofing felt and cement and resin injection systems.
•  Sports and Leisure - Silica sand is used for equestrian surfaces, in artificial turf, golf course root zones and dressings, football and cricket and other pitches and as play sands.
•  Other Uses - Silica has many other applications including the manufacture of chemicals and metals, fillers in numerous products, plastic and otherwise, the manufacture of refractories, stimulating oil production and as additives in agricultural and horticultural products. It is difficult to imagine a life without silica!
