· JVASP-54945· TmB6

Thulium hexaboride (TmB6) is a rare-earth metal hexaboride ceramic compound known for exceptional hardness and thermal stability at elevated temperatures. It is primarily investigated in research settings as a potential thermionic electron emitter and refractory material, belonging to a family of hexaborides that show promise for high-temperature applications where conventional metals and ceramics degrade, though it remains largely experimental compared to more established rare-earth ceramics.

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.
