· TiCoSb

TiCoSb is an intermetallic semiconductor compound combining titanium, cobalt, and antimony, belonging to the half-Heusler alloy family. This material is primarily investigated for thermoelectric energy conversion applications, where it can directly convert waste heat into electricity or enable solid-state cooling; it is notable for its potential to operate at elevated temperatures where conventional semiconductors degrade, making it attractive for recovering heat from industrial processes and vehicle exhaust systems. While currently in research and early development stages rather than high-volume production, TiCoSb and related half-Heuslers represent a promising alternative to lead-based and bismuth telluride thermoelectrics, particularly for applications requiring mechanical robustness, thermal stability, and reduced material toxicity.

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.
