· Na8 Sb8

Na8Sb8 is an experimental intermetallic semiconductor compound composed of sodium and antimony in an 1:1 stoichiometric ratio. This material belongs to the family of alkali-metal pnictogens and is primarily investigated in academic research for its electronic properties and potential applications in thermoelectric and optoelectronic devices. While not yet widely deployed in commercial applications, Na8Sb8 and related Zintl compounds are of interest to researchers exploring low-cost alternatives to conventional semiconductors for energy conversion and solid-state electronic systems.
