Chemistry of Silicon (Z=14)

The name for silicon is taken from the Latin silex which means flint. The element is second only to oxygen in abundance in the earth's crust and was discovered by Berzelius in 1824. The most common compound of silicon, (SiO_2), is the most abundant chemical compound in the earth's crust, which we know it better as common beach sand.

From Sand to Silicon

Sand – especially Quartz - has high percentages of Silicon in the form of Silicon dioxide (SiO 2) and is the base ingredient for semiconductor manufacturing. Melted Silicon – scale: wafer level (~300mm / 12 inch) Silicon is purified in multiple steps to finally reach semiconductor manufacturing quality which is called Electronic Grade Silicon.

Different Types of Casting Processes used in Manufacturing

A brief discussion of the different types of casting processes. Image credit: Funtay/Shutterstock. Casting manufacturing is a process in which liquefied material, such as molten metal, is poured into the cavity of a specially designed mold and allowed to harden. After solidification, the workpiece is removed from the mold to undergo various finishing treatments or for use as a final product.

Silica, also known as silicon dioxide, is an oxide of silicon, the 14th element on the periodic table of elements. After oxygen, silicon is the second most abundant element in the Earth's crust, however, it very rarely occurs in nature as its pure form. Rather, 90% of the Earth's supply of silicon occurs as silica.


Silicon is first converted into chlorosilanes, e.g. RSiCl 3, R 2 SiCl 2 and R 3 SiCl, where R is an organic group. When chloromethane is passed through heated silicon at about 550 K under slight pressure and in the presence of a copper catalyst (often copper itself but other copper-containing materials can be used, for example, brass or copper
