This is a list of silicon producers. The industry involves several very different stages of production. The industry involves several very different stages of production. Production starts at silicon metal, which is the material used to gain high purity silicon.
Elkem Solar estimates their UMG costs to be $25/kg, with a capacity of 6,000 tonnes by the end of 2010. Calisolar expects UMG technology to produce at $12/kg in 5 years with boron at 0.3 ppm and phosphorus at 0.6 ppm. [20] At $50/kg and 7.5 g/W, module manufacturers spend $0.37/W for the polysilicon.
These include hydrogenated amorphous silicon and upgraded metallurgical-grade silicon (UMG-Si) used in the production of low-cost, large-area electronics in applications such as liquid crystal displays and of large-area, low-cost, thin-film solar cells. Such semiconductor grades of silicon are either slightly less pure or polycrystalline rather ...
Since amorphous ribbon can be cast to any specific width under roughly 13 inches and can be sheared with relative ease, it is a suitable material for wound electrical transformer cores. In 2019 the price of amorphous steel outside the US is approximately $.95/pound compared to HiB grain-oriented steel which costs approximately $.86/pound.

Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, calcium silicides, and many other materials are used for the same purpose. [5]
