· CoTaN3

CoTaN₃ is a cobalt-tantalum nitride compound, likely an intermetallic or ceramic material in the refractory metal nitride family. This appears to be a research or developmental composition rather than an established commercial alloy; such cobalt-tantalum compounds are explored for applications requiring high hardness, thermal stability, and corrosion resistance in extreme environments.

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.
