· JVASP-97339· Dy2SiSeO4

Dy2SiSeO4 is a rare-earth silicate ceramic compound containing dysprosium, silicon, selenium, and oxygen. This material belongs to the family of mixed-anion ceramics and is primarily studied in research contexts for its potential in high-temperature applications and specialized optical or thermal properties. As a dysprosium-based ceramic, it is notable for incorporating selenium alongside traditional oxide components, making it a candidate material for environments requiring thermal stability and chemical resistance where conventional silicates may be insufficient.
