ZrNiSn is an intermetallic compound belonging to the half-Heusler alloy family, characterized by a specific crystalline structure combining zirconium, nickel, and tin. This material is primarily of research and emerging-technology interest, particularly for thermoelectric applications where the conversion of thermal gradients into electrical power is needed. The half-Heusler class has gained attention in recent years as a promising candidate for high-temperature thermoelectric devices and waste-heat recovery systems, offering potential advantages in thermal stability and mechanical robustness compared to traditional bismuth telluride-based thermoelectrics.
