· JVASP-14293· NaYSiO4

Sodium yttrium silicate (NaYSiO4) is an inorganic ceramic compound belonging to the silicate family, characterized by a crystalline structure combining rare-earth yttrium with sodium and silicate anions. This material is primarily investigated in research contexts for applications requiring thermal stability and optical properties, including phosphor hosts for luminescent applications, solid-state laser materials, and specialized refractories. Its yttrium content and silicate backbone make it a candidate for high-temperature environments where conventional ceramics may degrade, though it remains less widely commercialized than established alternatives like yttria or yttrium aluminum garnet (YAG).
