There are two main applications for Silicon Metal:

1.As an alloying element for aluminium alloys for casting and extrusions.

2.as the basic raw material for silicones produced by the chemical industry.

The remaining part of consumption is shared between ultra high purity electronic applications and solar applications.

The other uses remainmarginal.


Raw Material process of Silicon Metal:

  All Silicon Metal produced has its origin in quartz.Quartz is converted to silicon in a high temperature melting process usin carbon and large amounts of energy.


To create the qualities that are good enough for solar silicon,the silicon must be very clean,99.9999%.There are no quartz products that can be purified above 99.999% SIO2,therefore the silicon metal has to go through successive purification processes even if it is made of the purest quartz available.



It is normally made through a metallurgical process starting with lump quartz of medium to low purity together with carbon.This metallurgical silicon is upgraded though several cleaning processes into higher qualities like Solar Grade and Semiconductor grade.
