Products Description

The element with atomic number 14 naturally occurs in silicate minerals, including silica, feldspar, and mica, which are major components of common rocks such as quartz and sandstone. A semi-metal (or metalloid), silicon possesses some properties of both metals and non-metals.

Like water - but unlike most metals - silicon contracts in its liquid state and expands as it solidifies. It has relatively high melting and boiling points, and when crystallized forms a diamond cubic crystal structure. Critical to silicon's role as a semiconductor and its use in electronics is the element's atomic structure, which includes four valence electrons that allow silicon to bond with other elements readily.

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 1000-1500 megajoules of primary energy per kilogram to process high-grade silicon for computer chips or solar panels.

This is an excellent example (along with aluminum) of a material that is limited far more by how much energy is needed to make the substance usable (embodied energy) than the abundance on the planet. In other words there will never be a shortage of silicon for any use that people have conceived of; the energy to process it will always be the limiting factor.
