Ho4Sb3
ceramic· JVASP-57681· Ho4Sb3
Ho4Sb3 is an intermetallic ceramic compound belonging to the skutterudite family, characterized by a cage-like crystal structure that traps rare-earth and metalloid elements. This material is primarily of research and developmental interest for thermoelectric applications, where its unique phonon-scattering architecture enables high figure-of-merit values at elevated temperatures. Engineers consider skutterudites like Ho4Sb3 for waste-heat recovery and power generation systems where traditional thermoelectrics reach performance limits, though the material remains largely in the experimental phase compared to established commercial thermoelectric compounds.

Regulatory Screening
Environmental
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.
