· TbBe13

TbBe13 is an intermetallic ceramic compound combining terbium (a rare-earth element) with beryllium, forming a high-density ceramic material. This material is primarily of research and specialized industrial interest, investigated for applications requiring extreme thermal stability, neutron absorption properties, or unique electronic characteristics inherent to rare-earth intermetallics. While not widely deployed in mainstream engineering, TbBe13 represents the broader family of rare-earth beryllides studied for advanced nuclear, aerospace, and materials science applications where conventional ceramics or metals prove insufficient.

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.
