ScHgW2
metal· JVASP-51128· ScHgW2
ScHgW2 is an intermetallic compound composed of scandium, mercury, and tungsten, representing an experimental heavy-element alloy system with potential applications in high-density functional materials. This ternary metallic compound belongs to the family of exotic intermetallics and is primarily of interest in materials research rather than established industrial production. The material's notable characteristics—including its high density and unusual elastic properties—make it a candidate for specialized applications requiring density, thermal stability, or unique mechanical behavior in demanding environments.
