ErMg

ErMg is an intermetallic ceramic compound combining erbium (a rare-earth element) with magnesium, belonging to the family of rare-earth magnesium ceramics. This material is primarily of research interest rather than established industrial production, being studied for applications requiring thermal stability, hardness, or potential magnetoceramics functionality inherent to rare-earth-containing phases. Its use remains largely experimental, with potential applications emerging in high-temperature structural ceramics and advanced functional materials where rare-earth dopants can impart specialized electromagnetic or thermal properties.
