Structure and microstructure of In4Te3 nanopowders prepared by solid state reaction

► In and Te high purity powders were submitted to mechanical alloying process. ► In4Te3 nanocrystalline phase was nucleated in 2 h of synthesis. ► A non-reacted In still is present in final compound. ► The melting point for the In4Te3 and In decreased due to nanometer character. ► The In4Te3 phase is structurally stable even after one year of its production.
