· Yb12 Dy4 Sb12

Yb₁₂Dy₄Sb₁₂ is a rare-earth filled skutterudite compound, a class of intermetallic semiconductors characterized by a cage-like crystal structure with rattling rare-earth atoms. This material is primarily investigated in thermoelectric research for its potential to convert waste heat to electricity through the Seebeck effect, with the rare-earth filling fraction and composition tuned to reduce lattice thermal conductivity while maintaining electrical conductivity. The combination of ytterbium and dysprosium fillers offers opportunities to optimize phonon scattering and improve the figure of merit (ZT) compared to single-filler skutterudites, making it relevant for high-temperature power generation and waste heat recovery applications.

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.
