· O8 Er2 Ta2

O8Er2Ta2 is a rare-earth oxide ceramic composite containing erbium and tantalum oxides, likely developed as a high-performance refractory or advanced ceramic material for extreme-environment applications. This composition represents research-level development in the family of rare-earth stabilized ceramics, which are valued for their thermal stability, chemical resistance, and structural integrity at elevated temperatures. The combination of erbium and tantalum oxides suggests potential for specialized thermal barrier systems, aerospace components, or nuclear/high-temperature industrial equipment where conventional ceramics would fail.

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.
