· Sr8 Ge4

Sr8Ge4 is an intermetallic compound composed of strontium and germanium, belonging to the family of rare-earth-free semiconductors and thermoelectric materials. This material is primarily of research interest for thermoelectric energy conversion applications, where it offers potential advantages in converting waste heat to electricity without relying on scarce rare-earth elements. Sr8Ge4 and related strontium-germanium compounds are being investigated as alternatives to traditional lead-telluride and skutterudite thermoelectrics, particularly for mid-temperature power generation in industrial and automotive waste-heat recovery systems.

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.
