Mg2Si
semiconductorMg2Si is an intermetallic semiconductor compound combining magnesium and silicon, belonging to the family of binary semiconductors with potential thermoelectric properties. It is primarily investigated as a thermoelectric material for waste heat recovery and power generation applications, where its combination of mechanical rigidity and low thermal conductivity makes it attractive for solid-state energy conversion. Mg2Si remains largely in research and development phases rather than high-volume production, but represents a promising alternative to conventional thermoelectrics due to its abundance of constituent elements, lower cost potential, and environmental compatibility compared to lead-based or rare-earth competitors.
