Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
Herstellung von Silizium - Euroquarz GmbH
Silicium ist ein so genannter Halbleiter, d.h. ein Metall, das unter Zufuhr von Licht oder Wärme (Energiezufuhr von außen) elektrisch leitfähig wird (jedoch bei tiefen Temperaturen isolierend wirkt). Die Siliciumatome bilden ein stabiles Kristallgitter, wobei jedes Atom 4 Verbindungen mit den benachbarten Silicium-Atomen eingeht.
Sand mining - Wikipedia
Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded …

Silicon production: RW Silicium
Industrial silicon production. Large scale production of silicon is done by reduction of quartz with carbon. The necessary high temperatures of about 2000 °C are processed by an electric arc in a reduction furnace. A mixture of quartz and different carbon materials (coal, coke or charcoal) is continuously fed into the furnace. From the furnace tap hole liquid silicon is extracted with a ...
