metal· Zr0.5Hf0.5NiSn1.994Sb0.006
Zr₀.₅Hf₀.₅NiSn₁.₉₉₄Sb₀.₀₀₆ is a half-Heusler intermetallic compound combining zirconium, hafnium, nickel, and tin with trace antimony doping. This is a research-phase thermoelectric material designed to convert waste heat into electrical power through the Seebeck effect, with the dual-element Zr/Hf substitution and Sb doping used to optimize phonon scattering and electronic transport for improved energy conversion efficiency. The material belongs to a family of half-Heusler thermoelectrics being investigated for mid-to-high temperature energy harvesting applications where conventional thermal management is impractical.

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.
