· JVASP-38612· HoSb3

HoSb3 is a rare-earth antimonide ceramic compound composed of holmium and antimony, belonging to the skutterudite family of materials. This compound is primarily of research and development interest for thermoelectric applications, where its crystal structure and electronic properties are being investigated for potential use in solid-state heat-to-electricity conversion. Engineers and materials scientists study HoSb3 as part of broader efforts to develop high-performance thermoelectric materials for waste heat recovery and specialized cooling systems, though it remains largely experimental compared to commercial thermoelectric alternatives.
