Silicon

Silicon is a hard and brittle crystalline solid with a blue-grey metallic lustre; and it is a tetravalent metalloid and semiconductor.  Crystalline silicon is dark blue, brittle, and typically semiconductor.

There are two types of allotrope, one is dark brown amorphous powder, using magnesium to reduce silica, the nature is more active, can be burned in the air, known as amorphous silicon; Another stable crystal (crystalline silicon) is obtained by reducing silica in an electric furnace with carbon. Si is mainly in the form of oxygen-containing compounds.

VIMATERIAL specializes in producing high purity Silicon Granules in ultra high purity for analytical standards.

Applications:

Si is a semiconductor material that can be used to make semiconductor devices, solar panels, optical fibers and integrated circuits.

It can also be used in the form of alloys (such as ferrosilicon alloys) for automotive and mechanical parts.

Also used with ceramic materials in cermet.

Also used in the manufacture of glass, concrete, brick, refractory materials, siloxane, silane.

With iron union, can become siliceous steel, this is a kind of wear-resisting steel piece, commonly used on all sorts of tools.

In addition, si is one of the main components of stainless steel, which is used to make stainless steel wear resistant.
