· JVASP-21876· TmB4Rh

TmB4Rh is a rare-earth ceramic compound combining thulium, boron, and rhodium—a research-stage material synthesized for high-temperature structural applications. While not yet widely deployed in industrial production, this compound represents the boride ceramic family's potential for applications requiring exceptional thermal stability and metallic dopant reinforcement; its composite nature suggests investigation for extreme-environment uses where conventional ceramics or single-phase borides 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.
