HfNiSn is a ternary intermetallic compound combining hafnium, nickel, and tin, representing a research-phase material within the broader family of refractory metal intermetallics. This material is of primary interest in thermoelectric and high-temperature structural applications where its high density and thermally stable crystal structure may offer advantages, though it remains largely experimental with limited industrial deployment compared to established nickel-based superalloys or tungsten composites.
