· JVASP-41886· Sc2TcAu

Sc2TcAu is a ternary intermetallic compound combining scandium, technetium, and gold, representing a specialized research alloy rather than a widely commercialized engineering material. This material family sits at the intersection of refractory metallurgy and precious metal chemistry, offering potential in high-performance applications where corrosion resistance, thermal stability, and mechanical strength must be balanced with cost and scarcity constraints. Engineers would consider such materials only in niche, high-value sectors where conventional alternatives cannot meet extreme service conditions, though industrial adoption remains limited due to technetium's radioactivity and extreme rarity.
