· JVASP-94403· Mg2Sb

Mg₂Sb is an intermetallic ceramic compound belonging to the magnesium-antimony system, characterized by a rigid crystal structure with moderate stiffness. This material is primarily investigated in thermoelectric and semiconductor research contexts, where its electronic and thermal transport properties are of interest for waste heat recovery and solid-state cooling applications; it remains largely experimental rather than commoditized for mainstream engineering use.

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.
