· YAsO4

Yttrium arsenate (YAsO4) is an inorganic ceramic compound belonging to the rare-earth orthophosphate family. While not widely commercialized, this material is primarily of academic and research interest for its potential in optical and electronic applications, where rare-earth arsenates show promise as host matrices for luminescent dopants and in specialized sensor or photonic devices.
