Rheinfelden Carbon Products

What Rheinfelden Carbon Products does

Rheinfelden Carbon Products GmbH is a German specialty carbon products manufacturer headquartered in Rheinfelden, operating as a subsidiary of the Aluminium Rheinfelden diversified industrial group. The company produces electrode paste, calcined anthracite, and carbon quartz briquettes for silicon metal producers, ferroalloy producers, and operators of submerged arc furnaces globally. Its core product portfolio is anchored by the Elpa family of Soederberg electrode pastes (grades 30, 30L, 50, 50L, 50plus), composite variants (30Si, 50Si), an eco-grade line (Elpa Eco, Collar Paste KM green/eco), and LIMAK — a non-toxic electrode paste with PAH below 10 ppm and B[a]P below 1 ppm positioned as a first-of-its-kind product that removes SEVESO and MSDS obligations for downstream users.

Production technology centers on a vertical shaft furnace used for gas calcining anthracite at approximately 1200°C, supplemented by proprietary paste formulations and carbon quartz briquette technology engineered to reduce boron and phosphorus impurities in high-purity silicon smelting. The company combines this process IP with a tiered grade structure to serve varying furnace geometries and alloy chemistries.

The business model is direct enterprise field sales of industrial consumables to qualified smelter customers, with quote-based pricing on specialty carbon products. The company operates with 11–50 employees under a private GmbH structure within the Aluminium Rheinfelden Group, and is led by Matthias Ohlmer (Board of Management), Tanja Furrer (Head of Sales), and Dr. Fabian Brunner (Head of R&D). Revenue, pricing, and customer concentration are not publicly disclosed.

Core offering

Rheinfelden Carbon Products manufactures and sells carbon-based industrial products for the metallurgical sector, including gas calcined anthracite (produced in a vertical shaft furnace at approximately 1200°C), self-baking Soederberg and Composite electrode pastes, and ready-mixed carbon quartz briquettes. The portfolio includes an eco-friendly product line featuring LIMAK, the first non-toxic electrode paste with PAH below 10 ppm and no toxic classification. Products are sold directly to foundries and metal production facilities globally.

Product overview

Rheinfelden Carbon Products is a manufacturer of industrial carbon products operating as part of the Aluminium Rheinfelden Group. The product portfolio centers on carbon-based materials for metallurgical applications: Calcined Anthracite (gas calcined at 1200°C) serves as the foundational raw material; Soederberg Electrode Paste (branded as ELPA) and Composite Paste provide self-baking electrode solutions for submerged arc furnaces; Carbon Quartz Briquettes offer ready-mixed charges for silicon metal production. The eco product line includes LIMAK (non-toxic electrode paste with PAH below 10 ppm, no MSDS required) and Elpa Eco (treated coal tar pitch with reduced environmental hazard classification). These products serve aluminum and silicon metal production industries with specifications available for different furnace types.

Products and services

• Calcined Anthracite Gas calcined anthracite produced in a vertical shaft furnace at approximately 1200°C, providing a homogeneous end product with excellent grain stability and good physical properties. Used as a raw material for heavy-duty carbon products such as electrode paste, ramming paste, and carburizer in metal production.
• Soederberg Paste Self-baking electrode paste specifically formulated for Soederberg technology in submerged arc furnaces. Available in multiple quality grades including Elpa 30, Elpa 30L, Elpa 50, Elpa 50L, and Elpa 50plus to meet different furnace characteristics in ferroalloy and metal production.
• Composite Paste Electrode paste designed for composite furnace technology in silicon metal production. Based on anthracite, petcoke, and graphite. Available in various quality grades (Elpa 30Si, Elpa 50Si) with standard and high purity options.
• Carbon Quartz Briquettes Ready mixed and briquetized charge of quartz and carbon designed to reduce boron and phosphorus in silicon metal production. Enlarges reaction zone and facilitates removal of slag deposits during smelting.
• LIMAK First non-toxic electrode paste with new binder systems. B[a]P below 1 ppm, PAH (EPA 16) below 10 ppm, with no toxic classification. Available in 30Si and 50Si specifications. Eliminates the need for Material Safety Data Sheet and personal protection equipment for users.
• Elpa Eco Eco-friendly electrode paste with specially treated coal tar pitch. B[a]P below 300 ppm and Cantox equivalent 10 times lower than standard products. Not classified as environmentally hazardous, not a dangerous good, and has no SEVESO requirements. Successfully operated in industry since 2014.
• Collar Paste Eco-friendly collar paste available in KM green and KM eco variants for industrial furnace applications.
