About Silicon (Si)

Symbol: Si
Atomic number: 14
Atomic mass: 28.0855
Allotropes: amorphous Si, crystalline Si

Silicon is the most abundant electropositive element in the Earth's crust. It is a tetravalent metalloid that is more reactive than germanium, the metalloid positioned immediately below it in the periodic table.

Amorphous silicon appears as a brown powder, while crystalline silicon exhibits a metallic luster and a grey colour. Single crystals of crystalline silicon can be produced using the Czochralski method. Silicon carbide (SiC) has a hardness nearly equal to that of diamond and is employed as an abrasive. Silicon nitride is utilised in the manufacture of components for rolling bearings and cutting tools. It is also used for movable and wear parts in engines, turbine blades, shovels, cups, rollers and matrices for metal tube production.
