· YB66

YB66 is a rare-earth hexaboride ceramic compound, likely ytterbium hexaboride (YbB₆), belonging to the family of refractory boride materials used in high-temperature and electronic applications. This material is valued in specialized industries for its thermal stability, electrical conductivity, and refractory properties, making it particularly relevant where conventional ceramics would degrade. YB66 appears in thermionic emitters, high-temperature structural applications, and advanced electronic devices, though it remains less common than mainstream engineering materials and is often selected when extreme thermal environments or specific electrical performance requirements justify its 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.
