· YbB66

YbB66 is a rare-earth hexaboride compound belonging to the boride ceramic family, where ytterbium (Yb) is incorporated into a boron-rich lattice structure. This material is primarily of research and emerging-technology interest, valued for its potential as an electron emitter and in thermionic applications due to the electrical and thermal properties characteristic of rare-earth hexaborides. YbB66 represents an alternative to more established hexaborides (such as LaB6) for specialized high-temperature electron sources and may find applications in vacuum electronics, plasma generation devices, and advanced thermal management systems where rare-earth boride performance advantages justify material cost and processing complexity.

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.
