· JVASP-94960· HgB6

HgB6 is a hexaboride ceramic compound combining mercury with boron in a 1:6 stoichiometric ratio, belonging to the rare-earth and alkaline-earth hexaboride family of refractory materials. This material is primarily of research and specialized industrial interest for high-temperature applications where its thermal stability and ceramic properties offer potential advantages, though it remains less commonly deployed than alternative hexaborides like LaB6 or CeB6. HgB6 is investigated for thermionic emission, refractory coatings, and specialized electrochemical applications where its unique boride chemistry may provide benefits in extreme thermal or chemical environments.

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.
