· In0.3Co4Sb12

In0.3Co4Sb12 is a cobalt antimonide skutterudite compound with indium filling fraction, belonging to the class of thermoelectric materials. This is a research-phase material studied for its potential in solid-state heat conversion applications, where the filled skutterudite structure is engineered to reduce lattice thermal conductivity while maintaining electrical conductivity. Skutterudites like this composition are investigated as alternatives to traditional thermoelectrics for mid-to-high temperature power generation and waste heat recovery, with particular interest in automotive exhaust systems and concentrated solar thermal 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.
