· Ca2.97Na0.03AlSb3

Ca₂.₉₇Na₀.₀₃AlSb₃ is a doped calcium-based antimonide compound, a member of the III-V semiconductor and thermoelectric material family. This is a research-phase material where minimal sodium doping modifies the electronic structure of the calcium antimonide base compound. Such materials are investigated primarily for thermoelectric energy conversion applications where modest thermal conductivity combined with electronic doping can enhance figure-of-merit for waste heat recovery, though industrial deployment remains limited and the composition is not yet a commercial standard.

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.
