AMG produces silicon metal products are used primarily in the energy, chemical, electronics, aluminum industries. AMG produces high purity silicon metal (greater than 99% purity) and its byproducts through its investment in Graphit Kropfmühl. Silicon metal is the basic building block for silicones used in building materials, polysilicon used in solar and semiconductor wafers and as an alloying agent for aluminum. Microsilica, the primary by product of silicon metal production, is used in cement for building materials and as an additive to ceramics and refractory products.
