Sm1 Mg1 Hg2

Sm₁Mg₁Hg₂ is an intermetallic compound combining samarium (a rare-earth element), magnesium, and mercury. This is a research-phase material studied primarily in solid-state chemistry and materials science contexts rather than an established commercial alloy. The compound belongs to the family of rare-earth intermetallics and is of academic interest for understanding phase diagrams, crystal structures, and potential electronic or magnetic properties in ternary systems; industrial applications remain largely unexplored due to mercury's toxicity concerns and the lack of demonstrated performance advantages over established alternatives.
