Source high-purity Yellow Tungsten Oxide (CAS 1314-35-8) from Scimplify, one of the trusted global tungsten oxide suppliers and manufacturers. Yellow Tungsten Oxide, or Tungsten Trioxide (WO3), is the most stable and commercially prevalent oxide of tungsten. Within the Metallurgy, Speciality Chemicals, and Advanced Materials hierarchies, YTO is the primary "refined" chemical form. Produced via the calcination of Ammonium Paratungstate (APT), Tungsten Trioxide serves as the essential starting point for hydrogen reduction into pure tungsten metal powder and is increasingly sought after for its unique electrochromic and photocatalytic properties.As one of the authoritative tungsten oxide suppliers, we ensure our material meets global regulatory standards, including REACH (EU) registration and RMI conflict-free mineral sourcing protocols. We supply Yellow Tungsten Oxide in purity grades from industrial through 99.99 percent, with Fisher Sub-Sieve Sizer (FSSS) particle sizes matched to your application.WO3 also sits within Scimplify's integrated tungsten intermediates range, alongside Sodium Tungstate, Ammonium Paratungstate, and Tungstic Acid, so you can source across the tungsten value chain from a single compliant global tungsten oxide manufacturer.

Ultra-high-purity WO₃ (99.99%+, 4N) is pressed into sputtering targets for thin-film deposition in displays, optoelectronics, anti-reflective and IR-control coatings, and semiconductor manufacturing, where oxygen stoichiometry and trace-metal control are critical.
The largest use. WO₃ is reduced under hydrogen to tungsten metal powder, then carburised into tungsten carbide for cutting tools, mining and drilling inserts, dies, moulds, and wear parts. The particle size of the WO₃ directly governs the grain size of the powder, which sets carbide hardness and toughness — fine FSSS grades for micro-grain carbides, coarser grades for tougher mining parts. (Grade: 99.9–99.95%)
WO₃ serves as a non-corrosive, thermally stable catalyst for hydrodesulfurization, oxidation, and organic synthesis, a broad global requirement as low-sulfur fuel standards and cleaner-process mandates spread across refining markets. (Grade: 99.9%+)
WO₃ is the promoter in the dominant catalyst for removing NOₓ from flue gas, used across power generation, cement, steel, and waste-to-energy. Demand is global and recurring, driven by tightening air-emission regulations and spent-catalyst replacement cycles. Buyers specify high purity and surface area for uniform loading.
WO₃ is the benchmark electrochromic material, holding roughly half the active-material market, switching clear to blue under voltage in smart façades, skylights, automotive sunroofs, and mirrors. Growth is global, tied to energy-efficient building and vehicle adoption. Buyers need high-purity material suited to coating, sol-gel, or thin-film routes.
Highly stable at room temperature. Insoluble in water and most acids but dissolves in hot alkaline solutions
Store in a cool, dry place. Keep containers tightly closed. While not hygroscopic, preventing moisture ingress ensures the powder remains free-flowing for automated dosing.
Non-hazardous for transport. Available in 1000kg "Big Bags" for large-scale industrial supply
Yellow Tungsten Oxide (W O3) is fully oxidized. Blue Tungsten Oxide (BTO) is slightly reduced (sub-stoichiometric). BTO is often preferred for metal powder production because it reduces more quickly and easily in hydrogen furnaces, but YTO is the standard for chemical, ceramic, and electronic applications.
Particle size is measured via Fisher Sub-Sieve Sizer (FSSS). We offer grades ranging from 0.5 um to 20 um. We control the calcination temperature of the APT precursor to ensure the YTO morphology matches your specific metallurgical or catalytic requirements.
Yes. We provide ultra-high purity grades (99.99%+) specifically for the production of sputtering targets used in thin-film deposition for displays and semiconductor devices.
Absolutely. As with all our tungsten products, the raw ore is sourced from Conflict-Free Smelter Program (CFSP) compliant mines. We provide full RMI documentation to support your sustainability reporting.
