Silica sand or quartz sand:Quartz particles (SiO2) with a size between 2.00 and 1.05 mm, formed as a result of disintegration of magmatic metamorphic rocks rich in quartz. Quartz sand is white, while sands containing iron oxides have colors that range from pink to red or brown. Quartz sand is made of silica and may contain low levels of clay, feldspar, iron oxides and carbonates.
Chemical formula: SiO2
Application: Glass, glass fiber, insulation, aerated concrete, casting, ceramics, chemicals, silicates, CTP pipes, construction and building chemicals, filling, filtration, sport facilities, abrasives, cement.
