· JVASP-105831· NdAs3

NdAs₃ is a rare-earth arsenide ceramic compound belonging to the family of lanthanide pnictides, characterized by a zinc-blende or related crystal structure. While primarily of research interest rather than established commercial production, this material is investigated for potential applications in high-temperature electronics, thermoelectric devices, and infrared optics where rare-earth compounds offer unique band structure and phonon properties. Engineers consider rare-earth arsenides when conventional semiconductors or ceramics cannot meet requirements for extreme thermal stability, specialized optical response, or high-temperature electrical performance in niche applications.
