· JVASP-16557· TlHg

TlHg is an intermetallic ceramic compound composed of thallium and mercury, representing a rare combination of two heavy elements with interesting bonding characteristics. While not widely commercialized, this material belongs to the family of heavy-element ceramics and intermetallics that are primarily of research interest for studying exotic material properties and phase behavior. The compound's notably high density and unusual elastic properties make it relevant to specialized applications in radiation shielding, high-density materials research, and fundamental studies of mercury-based intermetallic systems, though practical engineering use remains limited due to toxicity concerns with both constituent elements and processing challenges.
