· JVASP-2379· Pr2SeO2

Pr2SeO2 is a rare-earth oxide-selenide ceramic compound combining praseodymium with selenium and oxygen, representing a specialized material class typically developed for research applications in advanced ceramics and functional materials. This compound belongs to the family of rare-earth mixed-anion ceramics, which are investigated primarily for their potential in high-temperature applications, electronic devices, and specialized optical or magnetic systems where conventional ceramics reach performance limits. While not yet widely adopted in mainstream industrial production, materials in this family are of interest to researchers exploring thermal stability, ionic conductivity, and electromagnetic properties for next-generation energy storage, sensing, or catalytic applications.
