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.
