· Er4 B16

Er4B16 is a rare-earth erbium boride ceramic compound belonging to the family of rare-earth hexaborides, which are known for their high melting points and electron-emission properties. This material is primarily investigated for thermionic emission applications and high-temperature structural uses where conventional metals and ceramics reach their limits. Er4B16 represents an emerging material class with potential in extreme-environment devices, though industrial adoption remains limited compared to established alternatives like lanthanum hexaboride.

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.
