· CeHg

CeHg is an intermetallic ceramic compound combining cerium and mercury, belonging to the family of rare-earth mercury intermetallics. This material is primarily of research interest rather than established industrial production, explored for its unique electronic and structural properties that arise from the interaction between cerium's f-electron behavior and mercury's metallic characteristics. Applications are limited to specialized research contexts, particularly in studying rare-earth intermetallic phase behavior, electronic properties relevant to advanced materials discovery, and potential use in high-pressure physics experiments where mercury-based compounds exhibit unusual phase transitions.
