· JVASP-78818· DyHg2

DyHg2 is an intermetallic ceramic compound combining dysprosium (a rare-earth element) with mercury, belonging to the class of rare-earth mercury intermetallics. This material is primarily of research interest rather than established industrial production, with potential applications in electronic and thermal management systems where the combination of rare-earth properties and metallic bonding characteristics may offer unique electromagnetic or thermoelectric behavior.
