· Ca2.85Na0.15AlSb3

Ca2.85Na0.15AlSb3 is an experimentally synthesized intermetallic compound belonging to the rare-earth-free Heusler or anti-Heusler family, combining alkaline earth metals (calcium, sodium) with aluminum and antimony in a structured lattice. Research compounds of this class are investigated for thermoelectric applications where low thermal conductivity and electronic structure control are priorities, as well as for magnetic or quantum materials research where compositional engineering of electronic bands is exploited. The partial sodium substitution for calcium represents a doping strategy to tune electronic properties and thermal transport, making it relevant to solid-state physicists and materials engineers exploring next-generation heat-to-electricity conversion or semiconducting compounds with tailored band structures.

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.
