· Zr0.5Hf0.5NiSn1.998Sb0.002

Zr₀.₅Hf₀.₅NiSn₁.₉₉₈Sb₀.₀₀₂ is a half-Heusler intermetallic compound combining zirconium, hafnium, nickel, and tin with trace antimony doping. This is a research-stage thermoelectric material designed to convert thermal energy directly into electrical energy through the Seebeck effect, with the Sb dopant tuning carrier concentration for optimized performance. Half-Heusler compounds in this family are investigated for medium-temperature waste heat recovery and power generation applications where conventional thermal solutions are impractical, offering potential advantages in terms of mechanical robustness and material abundance compared to traditional bismuth telluride-based thermoelectrics.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
