Refining Silicon | PVEducation

Ideally the silica has low concentrations of iron, aluminum and other metals. The silica is reduced (oxygen removed) through a reaction with carbon in the form of coal, charcoal and heating to 1500-2000 °C in an electrode arc furnace. SiO 2 + C → Si + CO 2 The resulting silicon is metallurgical grade silicon (MG-Si).

4 Igneous Processes and Volcanoes - An Introduction to Geology

4.1.3 Igneous Rock Bodies. Igneous rocks are common in the geologic record, but surprisingly, it is the intrusive rocks that are more common. Extrusive rocks, because of their small crystals and glass, are less durable. Plus, they are, by definition, exposed to the elements of erosion immediately. Intrusive rocks, forming underground with larger, stronger crystals, are more likely to last.
