· V3As

V₃As is an intermetallic compound in the vanadium-arsenic system, classified as a metal with a crystal structure characteristic of transition-metal-based intermetallics. This material belongs to a family of hard, refractory compounds that are primarily of research and development interest rather than established commercial production. V₃As and related vanadium-arsenic phases are investigated for potential applications requiring high hardness, thermal stability, or specialized electrical properties, though practical deployment remains limited due to brittleness, arsenic toxicity concerns, and processing challenges inherent to intermetallic phases.
