WO2.722

ceramic

· WO2.722

WO2.722 is a tungsten oxide ceramic with a non-stoichiometric composition, part of the Magnéli phase family of reduced tungsten oxides. These materials exhibit mixed-valence tungsten cations and are primarily investigated for applications requiring selective thermal and optical properties, including energy harvesting, gas sensing, and catalytic systems. WO2.722 is notable in research contexts for its semiconducting behavior and potential in thermoelectric devices or photocatalytic applications where intermediate oxidation states between WO2 and WO3 offer advantages over fully oxidized or fully reduced alternatives.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
