Synthesis of intermetallic zinc antimonide phases via low temperature solution route was investigated. Trial experiments were carried out under inert atmosphere at 70 °C using metallic Zn, SbCl3 and NaBH4 as reactants and tetrahydrofuran (THF), dimethylsulfoxide (DMSO) as organic media. Powder X-ray analysis confirmed the nucleation and growth of ZnSb phases in presence of excess Zn. SEM analysis revealed the existence of core–shell structure comprising of Zn core and Sb shell. Such particles get transformed into Zn4Sb3 crystalline phases upon thermal treatment at 300 °C/6 h in a silica tube closed under high secondary vacuum.
