· JVASP-141201· YbCo4P12

YbCo4P12 is a ternary intermetallic compound belonging to the skutterudite family, characterized by a cage-like crystal structure with ytterbium atoms nested within cobalt-phosphorus frameworks. This is a research-phase material primarily investigated for thermoelectric and low-temperature physics applications, where the rattling behavior of the ytterbium atoms within the cage structure can reduce lattice thermal conductivity while maintaining electrical conductivity. Engineers and materials scientists select skutterudites like YbCo4P12 for next-generation waste heat recovery systems and cryogenic applications where traditional thermoelectrics fall short, though industrial adoption remains limited pending improvements in mechanical stability and manufacturing scalability.

Export Control

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.
