    Tungsten Oxide (BTO/YTO) — Taiwan

    Taiwanese electrochromic material researchers and specialty ceramic manufacturers — within Taiwan's advanced technology materials sector, including research groups at ITRI (Industrial Technology Research Institute) and university-affiliated labs — use yellow tungsten oxide (YTO/WO₃) as an electrochromic precursor and catalyst support material, while blue tungsten oxide (BTO) serves as the reduction intermediate in W powder production. Both forms (~79% W content, fine calcined powder) are supplied by Jayanth Tungsten per order specification, with complete composition data on the certificate of analysis for Taiwanese chemical and materials company incoming qualification under HS 2825.

    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.

    Do you supply sub-micron WC powder for PCB micro-drill carbide grades?

    Yes. Jayanth Tungsten supplies WC powder in F.S.S.S. ranges from 2.5 µm upward; for sub-micron PCB micro-drill grades (F.S.S.S. 0.6–1.5 µm) please contact us with your specification for availability. All grades ship with full chemistry CoA under HS 2849 to Kaohsiung or Keelung with transit of 12–16 days from Nhava Sheva.
