semiconductor

· Ce1 B6

CeB₆ is a rare-earth hexaboride ceramic compound belonging to the family of transition metal borides, characterized by a simple cubic crystal structure with exceptional hardness and thermal stability. This material is primarily of research and specialized industrial interest, valued for its use in thermionic electron emitters (cathodes in electron microscopes and X-ray tubes) due to its low work function, and explored for high-temperature structural applications, refractory systems, and potential thermoelectric devices where its combination of mechanical strength and electronic properties becomes advantageous.

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.
