· JVASP-123252· Er3Ta

Er3Ta is an erbium tantalum ceramic compound belonging to the rare-earth intermetallic family. This material combines the refractory properties of tantalum with the thermal and optical characteristics of erbium, making it of research interest for high-temperature applications and specialized optical systems. Er3Ta represents an emerging ceramic rather than a commodity material, and its selection would typically be driven by specific requirements in extreme-environment or photonic applications where conventional refractories fall short.

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.
