Fused quartz is developed by melting crystalline silica in sand or stone form. Often used in the same applications as fused silica, it has a significantly lower OH content. Fused quartz possesses a high degree of purity, high chemical resistance, good thermal shock resistance, and low thermal expansion coefficient. Fused Quartz Silica Glass transmits ultraviolet very well, making it useful for ...

Quartz sand is an important raw material for nearly 100 kinds of industrial products, such as glass, electronics and electrical appliances, optical fiber semiconductors, water treatment, mechanical casting, artificial quartz stone, daily ceramics, metallurgy, superhard materials, chemical industry, cement, functional fillers, oil drilling and so on.
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 silica in the sand will normally be in the crystalline form of quartz. For industrial use, pure deposits of silica capable of yielding products of at least 95% SiO2 are required. Often much higher purity values are needed. Silica sand may be produced from sandstones, quartzite and loosely cemented or unconsolidated sand deposits. High grade silica is normally found in unconsolidated ...
