· JVASP-18660· CeHg2

CeHg2 is an intermetallic ceramic compound composed of cerium and mercury, belonging to the class of rare-earth mercury compounds. This material is primarily of research interest rather than a production commodity, studied for its unique electronic and structural properties that arise from the interaction between rare-earth and mercury elements. Industrial applications remain limited, though such compounds are investigated in condensed-matter physics for potential use in advanced electronic devices, magnetic systems, and specialized catalytic applications where the cerium-mercury coupling provides unconventional material behavior.
