Products Description
How is silicon metal produced?
The inputs to refining or smelting silicon metal are quartz sand and coke (carbon). The high temperature refining (silicon has a melting point of 2570°F) process is energy intensive – requiring approximately 13,000 kilowatt-hours per ton of silicon metal produced. The major producers have direct access to quartz mines and low cost energy.
What are some of the uses of silicon metal? *
25 to 30% of silicon metal output is required to make polycrystalline silicon for the semiconductor and solar industry.
45 to 55% of silicon metal is refined for metallurgical grade silicon used to make aluminum alloys or 'Silumin' – lightweight and strong metal alloy for the automotive and transportation sectors.
Only 25 to 30% of silicon metal is further refined through a hydro-metallurgical process to make chemical-grade silicon metal for silicone rubber and silanes.
