· JVASP-105198· Mg2As

Mg₂As is an intermetallic ceramic compound combining magnesium and arsenic, belonging to the family of binary metal-arsenide ceramics. This material is primarily of research and academic interest rather than established industrial production, as it exhibits characteristics typical of brittle ceramic intermetallics—making it relevant to materials scientists studying phase diagrams, crystal structures, and electronic properties of magnesium-based compounds. Interest in magnesium arsenides centers on potential applications in semiconductor research, thermoelectric devices, and fundamental studies of metal-pnictide chemistry, though practical engineering use remains limited compared to more developed ceramic systems.
