· Ta0.67Zr1.33O1.89N1.63

Ta0.67Zr1.33O1.89N1.63 is a tantalum-zirconium oxynitride ceramic compound, representing a mixed-metal nitride material that combines refractory metal elements with interstitial nitrogen and oxygen. This is a research-stage material synthesized to explore the properties of high-entropy or multi-component nitride ceramics, offering potential advantages in thermal stability, hardness, and chemical resistance compared to single-phase ceramic systems. The tantalum-zirconium base provides inherent corrosion resistance and high melting behavior, while the oxynitride stoichiometry enables tuning of electronic and mechanical properties for semiconductor and refractory applications.

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.
