What RW Silicon does
RW silicium GmbH is a German manufacturer of metallurgical silicon headquartered in Pocking, Lower Bavaria, and the only raw silicon producer in Germany. Founded in 1947, the company operates electric arc furnaces that reduce quartz with carbon at approximately 2,000°C to produce liquid silicon at around 1,600°C, followed by oxidative refining, casting, crystallization, and crushing. The site employs approximately 120 people and runs four furnaces with a stated annual production capacity of approximately 31,000 metric tons following the 2009 revamp of furnace No. 4.
The company's product portfolio centers on metallurgical silicon metal in four purity grades (Si-Metall 97 at ~97% Si, Si-Metall 441 and 3303 at ~99% Si with varying Fe/Al/Ca tolerances, and Si-Metall 2202 at 99.5% Si with low-iron chemistry), silicon powder at 0/200 micron particle size, and a silica fume (Mikrosilica) byproduct line marketed as RW-Füller (undensified), RW-Compasil (densified), RW-Flusil (aqueous dispersion), and RW-Füller Q1 (higher-grade). Additional secondary products include electrode residuals, graphite and carbon electrode breaks, tapping blocks, charcoal dust, and quartz sand. Silica fume is captured from furnace off-gas through a system of filter baghouses totaling over 1.6 million m³/h of off-gas handling capacity, and is sold into ceramics, refractories, fiber cement, and specialty concrete applications.
RW silicium runs a direct-to-customer business model through an in-house sales and shipping department, selling in bulk, bags, or bigbags to industrial buyers in the DACH region. End-markets are the chemical industry (silicone chemistry, microelectronics, solar silicon), aluminum foundries (alloying metal), construction materials manufacturers, and electronics/solar producers. The company is a wholly-owned subsidiary of AMG Mining GmbH, itself part of Amsterdam-listed AMG Advanced Metallurgical Group N.V., alongside sister company Graphit Kropfmühl GmbH. The firm holds ISO 9001 quality management, DIN EN ISO 50001:2018 energy management (both valid through 2027), and the Bavarian "Sicher mit System" workplace safety certification (valid through 2028). Pricing is not publicly disclosed.

RW Silicon product offering
Product offeringCore offering
RW silicium GmbH is Germany's only producer of raw (metallurgical) silicon, operating an electric arc furnace smelter at its Pocking site in Lower Bavaria. Founded in 1947, the company employs roughly 120 people and runs an annual production capacity of approximately 31,000 metric tons, supplying silicon metal in multiple grades, silicon powders, and microsilica (silica fume) products to industrial customers in the chemical, aluminum foundry, construction materials, and electronics/solar sectors.
Product overview
RW silicium GmbH is a German manufacturer of metallurgical silicon and related products. The company operates electric arc furnaces to produce silicon metal by reducing quartz with carbon. Their product portfolio centers on silicon metal (available in grades 97, 441, 3303, and 2202) and silicon powder (0/200 micron), which are used in the chemical industry for silicone production, microelectronics, solar energy, and as alloying metals in aluminum foundries. A significant portion of their business involves byproducts from silicon production: microsilica products (RW-Füller, RW-Compasil, RW-Flusil, and RW-Füller Q1) which are amorphous silica fume captured from furnace off-gases and used in refractories, special concretes, and fiber cement. Additional secondary products include electrode materials, tapping blocks, charcoal dust, and quartz sand. The company has operated since 1947 and is a 100% subsidiary of AMG Mining GmbH, part of the AMG Advanced Metallurgical Group N.V.

RW Silicon competitors and assessment
Company assessmentDirect peers
- Tokuyama Corporation: Japanese chemical company producing polycrystalline silicon for semiconductors and solar, plus silicon metal. Comparable to RW in silicon metallurgy and serves overlapping electronics and chemicals customers across Asia and globally.
- Mississippi Silicon LLC: US-based metallurgical silicon producer operating a single facility in Burnsville, Mississippi, with a focus on solar-grade silicon feedstock. Closely comparable to RW in production technology, single-site scale, target applications (silicons, solar, aluminum), and end-customer segments.
- Elkem ASA: Norwegian-based global producer of silicon products and ferrosilicon, owned by China National Bluestar. Directly competes with RW silicium in metallurgical silicon for chemicals, aluminum, and electronics markets, with similar production technology and overlapping customer base across European industrial buyers.
- PCC SE (PCC BakkiSilicon): PCC operates silicon metal production through its BakkiSilicon subsidiary in Iceland, leveraging low-cost geothermal power for electric arc furnace operations. Direct competitor to RW in metallurgical silicon with similar product range and customer base, but with a structural low-energy-cost advantage.
- Ferroglobe PLC: Ferroglobe is the world's largest publicly-listed producer of silicon metal and ferrosilicon, with operations across the US, Europe, South America, and Asia. The most direct comparable peer to RW silicium given overlapping silicon metal product portfolio, similar target customers (chemicals, aluminum, solar), and the same electric arc furnace production process.
- OCI Company N.V. Korean-Dutch producer of silicon metal and methanol, with US silicon operations through OCI Iowa. Competes with RW silicium in metallurgical silicon serving similar industrial customers (silicones, aluminum, solar), though OCI has a broader chemicals and fertilizer portfolio.
Broad incumbents
- Dow Inc. (Dow Silicones): Dow is a major global silicones producer and a significant consumer of metallurgical silicon feedstock. Comparable to RW as a vertically adjacent player in the silicon/silicone value chain, though Dow is not a direct silicon metal producer and operates at vastly larger scale with a diversified chemicals portfolio.
- Wacker Chemie AG: German chemical company producing polysilicon for semiconductors and solar, plus a major silicones business. Overlaps with RW silicium as a German specialty silicon player and is a significant customer for metallurgical silicon feedstock, while also competing at the higher-purity polysilicon tier.
Others
- Graphit Kropfmühl GmbH: RW silicium's sister company within the AMG Advanced Metallurgical Group, producing natural graphite for industrial applications. Comparable as a fellow specialty industrial materials producer in the same corporate group and sharing operational infrastructure knowledge, though graphite rather than silicon production.
Regional players
- Hoshine Silicon Industry Co., Ltd. Hoshine is the world's largest silicon metal producer, headquartered in China with massive integrated production. Comparable in core silicon metal production but operates at vastly larger scale, primarily serving Asia-Pacific markets rather than competing directly with RW in Europe — though it sets global silicon pricing benchmarks.
