ErSn2

ErSn2 is an intermetallic compound combining erbium (a rare-earth element) with tin, forming a ceramic-like metallic phase with potential high-temperature and electronic applications. This material belongs to the rare-earth tin intermetallic family, which has been studied primarily in research contexts for specialized functional properties rather than high-volume industrial production. The compound is notable for its potential in thermoelectric devices, magnetic applications, and high-temperature structural uses where rare-earth strengthening and tin's beneficial effects on phase stability are advantageous.
