Chemical Grade Silicon . Chemical grade silicon, when compared to metallurgical grade silicon, represents a step up along the refining process. The purity of chemical grade silicon ranges anywhere from 99-99.99%. The production of chemical grade silicon metal begins with the refining process of silica within quartz rock or sand.
Raw Materials Silicon metal is made from the reaction of silica (silicon dioxide, SiO2) and carbon materials like coke, coal and wood chips. Silica is typically received in the form of metallurgical grade gravel. This gravel is 99.5% silica, and is 3 x 1 or 6 x 1 in (8 x 3 cm or 15 x 3 cm) in size.
Quartz over time turns into Silica sand gradually because of the influence of water and wind. You have to use it when gradually it breaks into tiny granules. Silica sand or industrial sand is actually a type of high purity quality Silica Sand products. But it is actually sized controlling the material.

Silicon Carbide also has the resistivity necessary to perform as a semiconductor material. Because of these properties, Silicon Carbide is used in a wide range of applications and industries. Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open "Acheson" furnace.
Apr 11, 2020· Crystalline metallurgical silicon nanopowder was successfully produced from Tunisian silica sand by magnesiothermic reduction. Silica sand was first transformed into silica powder via a specific chemical process. The produced silica powder was reduced by magnesium granules at a temperature range of 500–800 °C. Thermal analysis shows that a low-temperature ramp rate (5 °C .
