· Zr0.98Nb0.02NiSn

Zr0.98Nb0.02NiSn is a Zirconium-Niobium-Nickel-Tin intermetallic compound, a research-phase material being investigated as a thermoelectric material for direct heat-to-electricity conversion applications. This composition represents an experimental variant of the half-Heusler ZrNiSn family, with niobium substitution intended to optimize phonon scattering and reduce thermal losses while maintaining reasonable electrical conductivity. The material is notable in the thermoelectric research community for potential use in high-temperature waste heat recovery where low thermal conductivity combined with adequate electronic transport properties is advantageous.

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.
