· Zr0.4Hf0.4Ti0.2NiSn

Zr0.4Hf0.4Ti0.2NiSn is a quaternary intermetallic compound belonging to the half-Heusler family, combining refractory elements (zirconium, hafnium, titanium) with nickel and tin. This is a research-stage thermoelectric material designed to operate at high temperatures, where its low thermal conductivity and electronic properties make it a candidate for solid-state heat-to-electricity conversion. Compared to conventional thermoelectrics, half-Heusler compounds like this composition offer improved mechanical robustness and thermal stability at elevated temperatures, making them relevant for waste-heat recovery and space power systems where traditional semiconductors would degrade.

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.
