The German company RW silicium GmbH is a manufacturer of metallurgical silicon. The silver coloured semi-metal is generated in a process whereby quartz and carbon are converted in electric arc furnaces. It is used in the chemical industry as a basic element for silicione chemistry, microelectronics and solar energy and furthermore it is utilized as an alloying metal in aluminium foundries.

Amorphous silicon dioxide (mikrosilica) is also obtained as a by-product during the manufacturing process. The so-called RW-Füller is used either as an uncompacted, high-grade microfiller – or compacted as RW-Compasil – in ceramic and refractory products as well as in fibre cement and special concretes.

RW silicium GmbH currently employs around 120 people.
