Dy2SeO2 is a rare-earth oxide-selenide ceramic compound combining dysprosium with selenium and oxygen, representing an emerging class of mixed-anion ceramics under active research. While not yet widely commercialized, materials in this family are investigated for high-temperature structural applications, optical devices, and advanced refractories, where the combination of rare-earth elements and mixed anionic frameworks offers potential advantages in thermal stability and specialized electronic properties compared to conventional oxides.
