· Zr0.99Nb0.01NiSn

Zr0.99Nb0.01NiSn is a half-Heusler intermetallic compound—a ternary metal alloy combining zirconium, niobium, nickel, and tin in a specific crystallographic structure. This is a research-stage thermoelectric material under investigation for its potential to convert waste heat into electricity, with the niobium doping designed to optimize phonon scattering and reduce thermal conductivity relative to the base ZrNiSn system. The material belongs to a family of candidates for mid-to-high temperature power generation and thermal management applications where conventional thermoelectrics are inadequate.

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.
