· JVASP-90582· Mg3Sb

Mg₃Sb is an intermetallic ceramic compound composed of magnesium and antimony, belonging to the family of binary metal pnictogens. This material is primarily of research and developmental interest for thermoelectric applications, where it shows potential for converting waste heat into electrical energy, particularly in automotive and industrial waste-heat recovery systems where its combination of low thermal conductivity and electronic properties may offer advantages over conventional thermoelectrics.

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.
