Hg3C

Hg₃C is a mercury-based intermetallic ceramic compound, representing a rare class of materials combining metallic and ceramic characteristics through mercury's interaction with carbon. This material exists primarily in research and specialized laboratory contexts rather than mainstream industrial production, and belongs to the broader family of metal-carbon intermetallics being investigated for fundamental materials science understanding and potential niche applications in extreme or corrosive environments where traditional ceramics or metals prove insufficient.
