Silica Sand - an overview | ScienceDirect Topics

To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and “autoclaved” at about 170°C (340°F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together. The main properties of these bricks are:Wanipigow Sand Extraction Project,This sand extraction project, i.e., the Wanipigow Sand Extraction Project (the ‘Project’) is being developed for the purpose of supplying high-quality silica sand for use in a variety markets such as oil and gas operations and the glass production industry.

Silica is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. In its capacity as a refractory, it is useful in fibre form as a high-temperature thermal protection fabric.
