Silica Sand
Benefits of Silica Sand. Supports significant onfield heat reduction. Round/subround particle shape allows the sands to "move" when in contact with the athlete, reducing abrasion tendencies injuries. 2040 round/subround sands work in conjunction with the artificial turf – supporting the turf blades against tears and cuts. Nonagglomerated (ie particles are "individual" not ...

SILICA
Silica (SiO2) is one of the most important rockforming minerals. It is to be found in magmatic, metamorphous as well as sedimentary rocks and deposits. Basically SiO2 appears in nature as trigonal silica. For industrial use, mighty, workable silica sand deposits are of decisive importance. Nevertheless, chemical purity and constancy are not ...
Reade Advanced Materials
The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. Silica is the most abundant mineral in the Earth's crust.
