· JVASP-50116· NdAsO4

NdAsO4 is a rare-earth arsenate ceramic compound containing neodymium as the primary metal constituent. This material belongs to the family of rare-earth orthophosphates and arsenates, which are primarily studied for their potential in nuclear waste immobilization, optical applications, and high-temperature structural ceramics. While not widely commercialized in mainstream engineering, NdAsO4 and related rare-earth arsenate compounds show promise as host matrices for actinide incorporation in nuclear waste forms and as components in specialized optical and refractory applications where chemical durability and thermal stability are critical.
