TANiOBIS GmbH

What TANiOBIS GmbH does

TANIOBIS GmbH is a wholly-owned subsidiary of Japan's JX Metals Corporation and a leading global developer and producer of high-quality metal powders, chlorides, oxides, and compounds based on tantalum and niobium. Operating from its headquarters and main production facility in Goslar, Germany, the company maintains additional manufacturing operations in Laufenburg (smelting and chloride production), Map Ta Phut, Thailand (hydrometallurgy and powder metallurgy), and Hitachi Ohmiya, Japan (Na- and Mg-reduced capacitor powders), plus sales offices in Tokyo and Needham, Massachusetts. The company's portfolio spans capacitor powders for electronics miniaturization, AMtrinsic® spherical gas-atomized powders (C-103, FS-85, Cb-752) for additive manufacturing of aerospace components, AMPERTEC® high-purity chlorides for semiconductor CVD/ALD precursors, oxides and niobates for optics and electroceramics, and nickel-niobium and other alloy additives for superalloys. Proprietary processes include the EIGA (Electrode Induction Melting Gas Atomization) method, in-house magnesium reduction for high-capacitance capacitor powders, a unique pyrometallurgical multi-stage process for producing synthetic concentrates from low-grade or secondary raw materials, and a two-step AMPERTEC® chloride production process.

TANIOBIS serves a B2B customer base across electronics and optics, aerospace and defense (jet engine nozzles, satellite thrusters, thermal protection), medical (implants and surgical instruments), energy (turbines), and chemical process industries, with no publicly disclosed end-customer logos. Its heritage traces to H.C. Starck, founded in 1920 in Berlin, with tantalum operations originating in 1951; the entity was acquired by JX Metals in 2018 and rebranded TANIOBIS in 2020. The company generates revenue through direct B2B sales via its regional offices in Germany, Japan, USA, and Thailand, supplemented by distribution partnerships such as the 2025 Elmet Technologies agreement for AMtrinsic® powders in North America; pricing is quote-based for custom-engineered material solutions, with no public pricing disclosed. Technology and customer qualification cycles in aerospace and capacitor applications create long switching cycles, while the vertically integrated chain from raw material processing through finished powders underpins cost and supply resilience.
