· In0.25Co4Sb12

In0.25Co4Sb12 is a cobalt-antimony skutterudite compound doped with indium, belonging to the family of cage-structured intermetallic materials engineered for thermoelectric applications. This experimental compound is specifically designed for solid-state heat-to-electricity conversion and refrigeration, where the rattling behavior of indium atoms within the skutterudite framework reduces phonon thermal transport while maintaining electrical conductivity. Engineers select skutterudite materials like this over conventional thermoelectrics for high-temperature power generation and waste-heat recovery systems where improved figure-of-merit and thermal stability are critical performance drivers.

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.
