LaAsON2

LaAsON₂ is an experimental ceramic compound combining lanthanum, arsenic, oxygen, and nitrogen—a rare quaternary nitride oxide that belongs to the family of advanced functional ceramics being explored for high-temperature and electronic applications. This material is primarily of research interest rather than established industrial use; it represents the broader class of oxynitride ceramics, which are investigated for potential applications in solid-state electronics, refractories, and semiconductor devices due to their mixed anionic bonding (N and O) that can tailor hardness, thermal stability, and electrical properties beyond conventional oxides or nitrides alone.
