Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a bluegrey metallic lustre, and is a tetravalent metalloid and is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not ...
Silicon is found in nature in the form of silicon dioxide (like some types of sand and many rocks). The extraction of silicon from silicon dioxide is extremely energy intensive; it requires megajoules of primary energy per kilogram to process highgrade silicon for computer chips or solar panels. This is an excellent example (along with aluminum) of a material that is limited far ...
Silicon can be mined from quartzite, mica, and talc, but sand is its most abundant ore source. The silicon in solar panels is manufactured through a reduction process in which the silica is heated with a carbon material and the oxygen is removed, leaving behind purer, metallurgicalgrade silicon.
The resulting silicon is metallurgical grade silicon (MGSi). It is 98% pure and is used extensively in the metallurgical industry. An even greater production of silicon is in the form of ferrosilicon that is manufactured using a similar process to that described above but is done in the presence of iron.
The major environmental impacts associated with silicon derive from its mining. Carbon monoxide is a byproduct of the basic process whereby silicon is prepared from silicon dioxide, but this is a negligible source of atmospheric carbon, compared to the amount generated by combustion of fossil fuels.
