· Na2 Zn2 Sb2

Na2Zn2Sb2 is a ternary intermetallic semiconductor compound composed of sodium, zinc, and antimony, belonging to the family of Zintl phases—complex ionic compounds where electropositive and electronegative elements form discrete polyanionic frameworks. This material is primarily of research interest for thermoelectric and optoelectronic applications, where its direct bandgap and crystal structure make it a candidate for studying phonon engineering and charge transport in solid-state devices. While not yet commercialized at scale, compounds in this family are attractive to materials scientists seeking alternatives to conventional semiconductors for waste-heat recovery and photovoltaic systems due to their tunable electronic structure and potential for earth-abundant element substitution.

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.
