H.C. Starck Tungsten Powders, a subsidiary of Mitsubishi Materials Corporation (MMC), is a global leader in the design, production, and supply of tungsten-based materials with over 100 years of expertise. Headquartered in Goslar, Germany, the company manufactures an extensive range of high-performance tungsten powders, oxides, carbides, and specialty compounds, meeting stringent industry standards across sectors such as automotive, aerospace, medical technology, and energy exploration.
Its product portfolio includes ultrafine to coarse grain sizes and proprietary solutions like starck2charge® for battery enhancement and starck2print® for additive manufacturing. By focusing on innovation, sustainability, and circular-economy principles, H.C. Starck provides tailored materials that combine exceptional strength, thermal resistance, and durability. The company’s commitment to recycling and raw material optimization is further exemplified by its EMAS certification and initiatives to recover tungsten from scrap, reducing environmental impact while ensuring supply chain efficiency.
Battery Technology
H.C. Starck plays a significant role in advancing battery technologies through its specialty tungsten powders. The starck2charge® line of products is engineered to enhance lithium-ion battery performance, improving stability, safety, and charging efficiency. These powders are designed to mitigate gas generation in cathode materials, extending battery lifecycles by preventing degradation. In collaboration with Germany’s Center for Solar Energy and Hydrogen Research (ZSW), the company is developing tungsten-based cathode coatings that suppress deleterious reactions, enabling faster charging rates and higher energy density.
In anode applications, H.C. Starck holds a 15% stake in British startup Nyobolt, which pioneered tungsten-doped anode materials capable of ultra-fast charging and high power output. Additionally, starck2print® tungsten powders are optimized for additive manufacturing, offering high flowability and precise particle distribution for 3D-printed battery components. These materials further enable closed-loop recycling systems by recovering tungsten from post-printing waste. The company’s recycling infrastructure, including plans for a large-scale lithium-ion battery recycling plant in Germany’s Harz region, aligns with its strategy to minimize reliance on primary raw materials, ensuring sustainable production while meeting strict environmental regulations.
Recent Projects
In early 2025, H.C. Starck announced plans to establish a lithium-ion battery recycling facility in Germany, supported by public and industrial funding to advance circular-economy principles. This project complements its ongoing collaboration with Nyobolt, where tungsten-based anodes for next-gen batteries are under development. The company also continued refining its proprietary recycling technology to recover tungsten from industrial byproducts and scrap, reducing energy consumption and waste.
Recent partnerships include deepening links with ChemiLytics GmbH for enhanced raw material processing and expanding its stake in research initiatives with the ZSW to optimize cathode coatings further. These efforts underscore H.C. Starck’s commitment to staying ahead in materials innovation while addressing global sustainability challenges.
Investors
H.C. Starck Tungsten Powders operates under the ownership of Mitsubishi Materials Corporation (MMC), which acquired the business in December 2024 following prior acquisitions by private equity firms Advent International and Carlyle Group, and later by Masan High-Tech Materials. MMC’s strategic investment, building on its 10% stake in Masan, positions H.C. Starck as a critical arm in its global tungsten and sustainability initiatives. The company’s equity stake in Nyobolt reflects its strategic investments in emerging battery technologies, directly aligning with its vision to strengthen advanced energy storage solutions.
