In this study, single phase polycrystalline Zn₄Sb₃ as well as 11 at.% Zn-rich Zn4Sb3 alloy having ε-Zn₄Sb₃ (majority phase) and Zn (minority phase) phases bulk samples produced by gas-atomization and subsequently consolidated by spark plasma sintering (SPS) process. The crystal structures were analyzed by X-ray diffraction (XRD) and cross-sectional microstructure were observed by the scanning electron microscopy (SEM). The internal grain microstructure of 11at.% Zn-rich Zn₄Sb₃ powders shows lamellar structure. Relative density, Vickers hardness and crack lengths were measured to investigate the effect of sintering temperature of Zn₄Sb₃ samples which are sintered at 653, 673 and 693 K. Relative density of the single phase bulk Zn₄Sb₃ sample reached to 99.2% of its theoretical density. The micro Vickers hardness of three different sintering temperatures were found around 2.17 – 2.236 GPa.
