· O4 Ta8

O4 Ta8 is a tantalum-rich oxide ceramic compound, likely a mixed-valence tantalum oxide phase used in specialized electronic and refractory applications. This material belongs to the tantalum oxide family, which is valued for high thermal stability, chemical inertness, and electrical properties useful in capacitors, thin-film devices, and extreme-environment components. Tantalum oxides are preferred in aerospace, medical implants, and high-reliability electronics where corrosion resistance and biocompatibility are critical, though this specific phase (O4 Ta8) may represent a research composition or proprietary designation with particular advantages in dielectric or catalytic performance compared to more common Ta₂O₅.

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.
