Products & Applications

Silicon metal is used, among other things, as an aluminium alloyant; it is also employed in the chemicals industry for the manufacture of siloxanes and silicones. Our silicon metal output is, to a large extent, already covered by long-term purchase agreements involving German companies as the primary customers, thus contributing to the security of raw material supplies to Germany.

Two byproducts are also part of the production process. These are silicon slag and MicroSilica. Both these product will be sold to customers around the world.
