· JVASP-106776· Mn4Hg3Au

Mn4Hg3Au is an intermetallic compound composed of manganese, mercury, and gold. This is a research-phase material primarily of academic interest, belonging to the family of precious metal intermetallics that combine gold's corrosion resistance with manganese's strength and mercury's unique alloying properties. Industrial applications remain limited; the material is studied for specialized high-density applications and as a model system for understanding phase behavior in complex ternary metal systems, though mercury's toxicity and volatility present significant barriers to widespread engineering adoption.
