· CaHg2

CaHg2 is an intermetallic ceramic compound containing calcium and mercury in a 1:2 stoichiometric ratio. This material belongs to the class of binary intermetallic compounds and is primarily of research and academic interest rather than established industrial production. CaHg2 represents an exploratory composition within mercury-based intermetallic systems, relevant to materials scientists investigating phase diagrams, crystal structure properties, and the mechanical behavior of heavy-metal compounds; engineers would consider this material only in specialized research contexts involving mercury chemistry or fundamental studies of intermetallic bonding, as commercial applications remain extremely limited due to mercury's toxicity concerns and regulatory restrictions.
