· Y2 Ta2 O8

Y₂Ta₂O₈ is a rare-earth tantalate ceramic compound combining yttrium and tantalum oxides, belonging to the family of high-temperature ceramic oxides. This material is primarily of research and development interest for advanced aerospace and thermal barrier applications, where its high melting point, chemical stability, and mechanical stiffness make it a candidate for extreme-environment coatings and structural components. Compared to conventional thermal barrier ceramics like yttria-stabilized zirconia, tantalate-based oxides offer enhanced oxidation resistance and potential for higher temperature service, though industrial adoption remains limited and material behavior is still being characterized.

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.
