ceramic

· NbTaO3

NbTaO3 is a mixed metal oxide ceramic composed of niobium, tantalum, and oxygen, belonging to the perovskite or related oxide ceramic family. This material is primarily of research and emerging-application interest, investigated for its potential in high-temperature structural applications, dielectric devices, and advanced capacitor technologies where the combination of refractory metals provides enhanced thermal stability and chemical resistance. Compared to single-metal oxides like Ta₂O₅ or Nb₂O₅, niobium-tantalum mixed oxides offer tailored electronic and thermal properties, making them candidates for specialized applications in aerospace, electronics, and materials requiring extreme environmental tolerance.

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.
