    Tungsten Oxide (BTO/YTO) — France

    French electrochromic glass researchers, advanced ceramics manufacturers, and specialty chemical companies — including Saint-Gobain Research (electrochromic and advanced glass research) and Solvay's materials division — use yellow tungsten oxide (YTO/WO₃) as the active electrochromic precursor and as a specialty catalyst support. Saint-Gobain's Sekurit and Sage Glass divisions have been active in electrochromic glazing, creating demand for high-purity WO₃ precursors. Both BTO and YTO (~79% W content, fine calcined powder) are supplied by Jayanth Tungsten under EU CN 2825 with REACH-supporting data per lot for French specialty material company incoming qualification.

    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 tungsten powder for French aerospace tooling manufacturers?

    Yes. Jayanth Tungsten supplies WC powder and tungsten metal powder to exacting specifications for aerospace tooling applications, with full ISO 9001:2015 documentation, REACH-compliant SDS, and per-lot certificate of analysis. Shipments clear EU customs at Le Havre or Marseille under CN 8101/2849 in 3–4 weeks from Nhava Sheva.
