NiAs5

NiAs₅ is a nickel arsenide intermetallic compound belonging to the transition metal pnictide family. This material is primarily of research and academic interest rather than established industrial production, with potential applications in semiconductor, thermoelectric, and catalytic domains where nickel-arsenic phases show promise. Engineers would consider this compound where extreme hardness, specific electronic properties, or catalytic activity in nickel arsenide systems are required, though commercial availability and processing routes remain limited compared to conventional nickel alloys.
