    Ammonium Paratungstate (APT) — Switzerland

    Swiss specialty chemical companies and pharmaceutical research organisations — including Lonza (Basel), Syngenta (Basel), and Swiss Federal Institutes of Technology (ETH Zurich, EPFL Lausanne) — source ammonium paratungstate (APT, WO₃ min. 88.5%, carbon max. 0.0010%, F.S.S.S. 30–70 µm) as the tungsten chemical intermediate for catalyst preparation, specialty oxide synthesis, and advanced materials research in Switzerland's world-class chemistry and materials science sector. Switzerland's pharmaceutical and fine chemical industry — one of the highest-value per-capita chemical industries globally — uses tungsten-containing catalysts in certain hydroprocessing and specialty synthesis applications. Jayanth Tungsten's APT is supplied in 25 kg fibre drums with full ICP chemistry CoA and HS 2841 documentation for Swiss customs clearance.

    Export questions

    What chemistry data is provided with APT shipments?

    Each lot's certificate of analysis states WO₃ content (min. 88.5%), carbon (max. 0.0010%), apparent density, and F.S.S.S. grain size, with the full impurity composition table as set out in our brochure available on request.

    Can you supply ultra-fine tungsten powder for Swiss watchmaking and precision component manufacturing?

    Yes. Jayanth Tungsten supplies W metal powder and WC powder in sub-micron to fine grades (F.S.S.S. 0.8–4 µm) for Swiss precision component and micro-machining applications. Full chemistry CoA (W min. 99.85%, O max. 0.06%, ICP impurity table) is provided per lot. Shipments clear Swiss customs at Basel under HS 8101/2849. Contact us for sample availability.
