Mo2O3

ceramic

· Mo2O3

Mo₂O₃ is a mixed-valence molybdenum oxide ceramic compound that exists primarily as a research material rather than a widely commercialized engineering ceramic. It belongs to the molybdenum oxide family and has been investigated for applications requiring high-temperature stability, electrical conductivity, and catalytic properties. The material is notable in catalysis research, thin-film electronics, and high-temperature oxidation resistance applications, where its intermediate oxidation state offers advantages over fully reduced (MoO₂) or fully oxidized (MoO₃) 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.
