ceramic

· JVASP-40516· TaGaOs2

TaGaOs2 is an experimental ternary oxide ceramic composed of tantalum, gallium, and osmium. This compound belongs to the family of advanced refractory oxides and is primarily of research interest rather than established industrial production. The material's potential lies in high-temperature applications and specialized electronic or photonic devices where the combination of transition metals can offer unique thermal stability, electrical, or optical properties not achievable with binary oxide systems.

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.
