· JVASP-7752· Dy2SO2

Dy2SO2 is an experimental dysprosium-based oxide ceramic compound combining rare-earth dysprosium with sulfur and oxygen. While not widely commercialized, this material belongs to the family of rare-earth ceramics studied for high-temperature and electronic applications where the unique properties of dysprosium—including neutron absorption and luminescent characteristics—can be leveraged. Dysprosium ceramics are of particular interest in nuclear, photonic, and advanced refractory applications where conventional oxides reach their performance limits.
