· Mg2Si0.98Bi0.02

Mg2Si0.98Bi0.02 is a doped magnesium silicide ceramic compound belonging to the Zintl phase family, modified with bismuth doping to engineer its electronic and thermal properties. This is a research-stage material developed to improve the thermoelectric performance of Mg2Si, which is industrially valued for its low cost, abundance, and stability at moderate temperatures compared to rare-earth-based thermoelectrics. The bismuth substitution is designed to optimize carrier concentration and reduce lattice thermal conductivity, making the material attractive for waste heat recovery systems and thermoelectric generators in automotive and industrial applications where conventional alternatives prove too expensive or insufficiently durable.

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.
