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. Source High-Purity Yellow Tungsten Oxide (CAS 1314-35-8) from Scimplify, your authoritative global manufacturer of refractory metal oxides. Our Yellow Tungsten Oxide (YTO) is a premium, high-surface-area tungsten trioxide engineered for precision metallurgy, high-performance catalysts, and advanced electronic applications. As an authoritative YTO supplier, we ensure our material meets global regulatory standards, including REACH (EU) registration and RMI conflict-free mineral sourcing protocols. Tungstic Anhydride material is the definitive precursor for tungsten metal powder production and is prized for its consistent particle size distribution. Whether you are manufacturing smart windows, ceramic glazes, or gas sensors, Scimplify delivers the chemical purity, international SDS/COA transparency, and reliable bulk logistics required for the global high-tech and industrial sectors.

Chemical Properties & Specifications
Most critical material for the production of Tungsten Metal Powder. Placed in reduction furnaces under a hydrogen atmosphere, where the oxygen is stripped away to leave pure metallic tungsten. Particle size of the YTO directly influences the grain size of the resulting metal powder, which is vital for high-quality tungsten carbide production
Unique ability to change color (from yellow/clear to deep blue) when an electric voltage is applied, a process known as electrochromism. Core material for Smart Windows that can dim automatically to reduce building energy consumption
Efficient photocatalyst used for water splitting (to produce hydrogen) and the degradation of organic pollutants in wastewater. Bandgap is well-suited for absorbing visible light, making it a sustainable choice for environmental remediation.
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.
