· MoTaO2N

MoTaO₂N is a transition metal oxynitride ceramic combining molybdenum, tantalum, oxygen, and nitrogen phases. This is a research-stage material within the broader family of high-entropy and complex oxynitrides, developed for applications demanding exceptional hardness, thermal stability, and corrosion resistance in extreme environments. Its mixed-valence composition and nitrogen incorporation offer potential advantages over conventional oxides and nitrides in wear resistance and high-temperature performance, though it remains primarily investigated in academic and advanced materials development settings rather than established industrial production.

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.
