· Mg2Si0.995Bi0.005

Mg2Si0.995Bi0.005 is a doped magnesium silicide ceramic compound, where a small amount of bismuth (0.5%) substitutes into the Mg2Si lattice. This is a research-phase thermoelectric material engineered to optimize phonon scattering and reduce thermal conductivity while maintaining electrical properties suitable for energy conversion applications. The bismuth doping represents an experimental approach to improving the figure of merit (ZT) of magnesium silicide, a candidate material for medium-temperature thermoelectric power generation where waste heat recovery and solid-state cooling are priorities.

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.
