    Tungsten Oxide (BTO/YTO) — Switzerland

    Swiss specialty ceramic manufacturers, watch case coating companies, and research institutions — including ETH Zurich's materials science department, EMPA (Swiss Federal Laboratories for Materials Science), and Swiss companies developing PVD tungsten oxide coatings for watch bezels and precision optical components — source blue tungsten oxide (BTO) and yellow tungsten oxide (YTO/WO₃, W content ~79%) for electrochromic device research, PVD target preparation, and as precursors for tungsten nanoparticle synthesis. Swiss watchmakers and precision opticians use WO₃-derived PVD coatings on display glass and lenses for their electrochromic and anti-reflective properties. Jayanth Tungsten supplies BTO and YTO per order with full composition CoA and HS 2825 documentation for Swiss import clearance.

    Export questions

    What is the difference between BTO and YTO for export orders?

    Blue tungsten oxide (BTO) is the sub-stoichiometric reduction intermediate (approx. WO2.72–WO2.9), while yellow tungsten oxide (YTO/WO₃) is the stoichiometric form. Both are supplied per order specification — confirm which form your process requires when requesting a quote.

    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.
