The value of silica sand is based on its chemical and physical properties other than high silica content. The presence of foreign objects such as clay, iron oxide and chromite must be avoided. Fe 2 O 3 will cause a certain colour to the glass industry while TiO 2 and Cr 2 O 3 do not melt in the process of glass making and produce black spots.

 · And it is this demand for silica sand (SiO2) that might prove to be a bit of a stumbling block. While silica sand is the most abundant mineral on the planet, it is still a finite resource. This is because high purity sand is required for making both flat glass and container glass as impurities such as sulphides and iron will cause imperfections.

 · In this paper, a method of deeply removing aluminum impurity from high purity quartz sand is shared. In sand washing and silica sand processing plant, Quartz sand contains many kinds of impurities, of which iron and aluminum are the most difficult to remove, so the content is high.Among these two impurities, especially aluminum is the most difficult to remove, so the content is the highest.

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.

High Silicon in Engine Oil Analysis. After oxygen, silicon is the most abundant element in the earth's crust. Silicon does not occur naturally in elemental form but rather combined with oxygen in a compound called silica (silicon dioxide). Silica occurs in a free form (quartz, sand, etc.) or combined with a variety of metallic oxides, in which .

However, a common cause of the above defects is the use of casting sands with reduced permeability, strength and high moisture content. This highlights the importance of using appropriate sands in the sand casting processes. While some green sands and dry sands stand out in strength, they do not satisfy all requirements of good casting sand.

Silica deposits are not a problem in most turbines where the silica content in the steam is below 0.02 ppm. Therefore, it has become customary to limit silica to less than 0.02 ppm in the steam. Sometimes, because of the more stringent operating conditions of certain turbines, vendors specify that steam silica be maintained at less than 0.01 ppm.
