· JVASP-50521· ErTa3O9

ErTa3O9 is a ternary oxide ceramic compound combining erbium and tantalum, belonging to the family of rare-earth tantalate ceramics. This material is primarily of research interest for high-temperature applications and advanced ceramic systems, with potential use in thermal barriers, refractory coatings, and specialized electronic or photonic devices where rare-earth dopants and tantalate-based matrices offer unique properties such as high melting points and chemical stability.

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.
